Introduction

Are y'all looking to add a lot of color to your project? These massive RGB LED panels are an awesome identify to start. Yous tin create animations, games, or all sorts of other fun displays with them. Depending on the manufacturer, these panels can come up in different sizes, LED pitch, and scan rates. Hither are the ones that SparkFun currently carries in the catalog:

• 1024 pixels (3072 total LEDs!) 32x32 pixel panel with 1:sixteen browse rate measuring 7.v"x7.5"
• 2048 pixels (6144 total LEDs!) 32x64 pixel panel with 1:sixteen scan charge per unit measuring 5x10"

Notation: The 16x32 version has been retired from our catalog, but we are keeping the data in the tutorial for reference.

In this tutorial we'll show y'all just how, exactly, these panels operate. We'll dig into the hardware hookup and examine how to best power them. So nosotros'll work up a demo sketch and control them with Arduino.

A 16x32 RGB LED panel to the left, and a 32x32 console to the right.

Required Materials

On superlative of either size console, yous'll too need:

• At least an Arduino Uno (or comparable ATmega328-based Arduino). These panels actually stretch the Arduino to its limits. If you take an Arduino Mega 2560 you may want to whip that out instead. Any size higher than a 32x32 panel requires an Arduino Mega 2560 or faster microcontroller.
• Two packs of male person-to-male person jumper wires. You'll demand effectually sixteen to wire from the console to your Arduino.
• A 5V power supply. You'll demand something that tin source a high corporeality of electric current. A simple 5V (1A) wall adapter does work, at least in the short run, but you may want to footstep up to a higher chapters supply, like the 12V/5V (2A) or 5V/2A wall adapter.
• You'll also demand some method to connect your ability supply to the panel. The panel includes a 4-pin polarized connector and spade-terminated cable for its power supply. Bank check out the adjacent folio for help finding a power source and cable.

Suggested Reading

Before post-obit along with this tutorial, nosotros recommend reading through these tutorials first:

What is an Arduino?

What is this 'Arduino' thing anyway? This tutorials dives into what an Arduino is and along with Arduino projects and widgets.

Low-cal-Emitting Diodes (LEDs)

Learn the nuts about LEDs too as some more advanced topics to help you lot calculate requirements for projects containing many LEDs.

Powering the Panel

Power Connector

These panels crave a regulated 3.3-5V supply for power. And that supply needs to be able to source a good corporeality of current -- upwards to 2A in the worst instance (all pixels bright, hot, white). For a 32x64, 1 of these panels was pulling about ~iii.36A-3.43A without a heat sink -- and so about up to 4A worst case. A 4-pin (two for VCC, 2 for GND), 0.fifteen"-pitch polarized connector should exist used to supply ability to the panel. Depending on the manufacturer, the color and location of the power connector may be different.

Ability Cablevision

Included with the panel is a dedicated cablevision for power. It's a 0.15" pitch 4-pin polarized connector. The included cable is terminated with both a female polarized connector, and a pair of spade terminals.

Here are a few methods we've used to power the panel. If you are powering the Arduino with a dissimilar voltage, make sure to connect GND in order to have the same reference voltage.

Longer-Term: 12V/5V Power Supply Breakout Board

This is our recommended philharmonic:

1. A 12V/5V 2A Power Supply, which should exist enough to continue the display running. (Just don't hook up the 12V output to information technology!). Notation: If you are using an older 12V/5V power supply, you will need the iii prong IEC C13 Cable to connect Air-conditioning power to the supply.
2. Breakout Board with Molex connector and 5mm screw terminals soldered. Note: The spade connector for the console's GND pivot tin can be connected to both GND pins of the screw terminal. Just brand certain to not connect it to the 12V or 5V side.
3. Strip two pieces of wire and connect a male person DC barrel jack adapter with a screwdriver to an Arduino's butt jack for VIN. Note: Well-nigh Arduinos should accept a voltage regulator that can handle the input between 7-12V, merely brand sure to cheque out the specs on the evolution board earlier powering up.

Your final connexion should look like to the closeup of the connection below with the LED panel's forked spade connector and wires inserted into the spiral terminals.

Longer-Term: 12V/5V Power Supply Splicing Wires

You lot tin can besides splice the wires using the following combinations:

1. A 12V/5V 2A Ability Supply, which should be enough to keep the display running. (Only don't hook upwards the 12V output to it!). Notation: If you are using an older 12/5V power supply, you lot volition need the iii prong IEC C13 Cable to connect AC power to the supply.
2. A four-pivot Molex Connector westward/ Pigtail to interface the supply to console.

The ingredients for our ability supply and cable.

To begin, we snipped the spade connectors off of the panel power supply cablevision. And then stripped the newly unterminated ends.

Then we spliced the Molex pigtail to the LED panel's power cable past connecting the red wires together. Practise the same for the black wires (make certain you use the black wire next to the red on the Molex pigtail). Make sure y'all are connecting to the 5V and GND pins and Not the 12V pin. Before connecting to the RGB Matrix Panel, test the connection with a multimeter.

Spliced Wires

Finally, embrace the splice with heat shrink or electrical tape, and voila! That's a beautiful power cablevision.

Finished panel power supply cable.

This is a dainty, sturdy interface between the panel and a solid ability supply. If y'all're looking for something easier, but less reliable cheque the below option.

Long-Term: Mean Well Switching Power Supply

For those that want to push the panels to the limit (i.e. setting the pixels on a 32x64 panel at full white at maximum capacity), combine:

1. A 5VDC/20A Mean Well switching power supply - which is more than plenty for your panel.
2. A wall adapter cablevision (N America or European standard) depending on your country.

Curt-Term: Barrel Jack

Catch a 5V wall adapter. Both been tested to work with the panels as well. At least in the brusk term.

• 5V/2A Wall Adapter
• USB 5V/1A Wall Adapter (with USB Barrel Jack Adapter)

Apply the ability supply in conjunction with a female barrel jack adapter and screwdriver to get a quick and dingy connection between the spade and barrel jack.

The terminal connection should wait similar the image below.

Hardware Hookup

Before we tin get into the lawmaking portion, there's quite a bit of wiring to do. The RGB panels have a pair of 16-pin (2x8) IDC connectors, and we need to wire up to virtually of those pins. Conveniently, both panels take the connector pins labeled (the unlabeled pins are footing). As we're hooking upwards to the console, brand sure you use the connector labeled Input . The labeling may be slightly different depending on the manufacturer.

Connector labels on a 32x32 console. 16x32 has the aforementioned layout, except that D is a no connect (NC) instead. 32x64 has the same layout just no labels.

Note to 16x32 Panel Users: The 32x16 panel has the exact same pinout as the 32x32, except there is no "D" pin. Instead of "D", that pin (12 on the connector) is a no connect (NC), y'all tin exit it alone.

Labels on 32x64 and 16x32 Panel Users: On top of that, some panels practise not have labels on the connector pins -- instead there is an arrow (◄) indicating pin 1, in the top-left corner of the connector (information technology's obscured past the frame, but visible if you lot peek in at the right angle). That pivot 1 arrow indicator points to the "R0" pin, and the pinout follows that of the 32x32 console from there. Nosotros have also seen panels come with their pins characterization G1, G2, R1, R2, B1 & B2 instead of G0, G1, R0, R1, B0 & B1. The wiring will be the same for both cases by connecting to the connector on the left.

Hookup Tabular array

Here are the pin connections betwixt LED console connector and Arduino:

Panel Pin Label	Cable Connector Pin #	Arduino Uno (Atmega328P) Pin	Arduino Mega 2560 Pin	Notes
R0	1	two	24	Red Data (columns 1-16)
G0	2	three	25	Green Data (columns 1-16)
B0	3	four	26	Blue Data (columns 1-16)
GND	iv	GND		Ground
R1	v	five	27	Carmine Information (columns 17-32)
G1	six	half-dozen	28	Light-green Data (columns 17-32)
B1	seven	vii	29	Blue Information (columns 17-32)
GND	viii	GND		Basis
A	ix	A0		Demux Input A0
B	10	A1		Demux Input A1
C	xi	A2		Demux Input A2
D	12	A3		Demux Input E1, E3 (32x32 panels only)
CLK	xiii	11		LED Drivers' Clock
STB	14	ten		LED Drivers' Latch
OE	xv	9		LED Drivers' Output Enable
GND	xvi	GND		Ground

For a more step-past-step approach, follow forth below. We utilise male-to-male premium jumper wires to wire between the included ribbon cable and our Arduino.

Connect Data Pins: R0, B0, G0, R1, G1, and B1

These LED driver (shift register) data pins are hard-coded in the Arduino library and can't be moved. Equally listed in the tabular array above, R0, G0, B0, R1, G1, and B1 go to the Arduino Uno'due south pins 2 through 7 respectively. If you lot're wiring the panel up to an Arduino Mega, these pins should be continued to pins 24-29 respectively.

For reference when wiring the pins, attempt looking downwardly at the IDC connector with carmine wire on top. The cable connector'south pivot 1 is relative to the elevation right. If you look really closely at the molding, y'all may also arrow (◄) pointing to that pivot. Also, note that the tab for polarity is on the right side on either cease of the cablevision.

IDC Connector Highlighted west/ Pointer Pointing to Pin ane

One time you decide what side to connect, start wiring pin 1 by connecting a red wire for R0. So connect pin two past connecting a green wire for G0. After connecting pin 3 using a bluish wire for B0, continue wiring the pins based on the hookup table.

To assistance keep rails of what side you are connecting to, feel gratuitous to label your connections with a marker.

Connecting the Clock Pivot

This is the last pin that has some brake on where it can go -- it must be connected to one of Arduino's port B pins. That ways information technology must be either viii, 9, ten, eleven, 12, or thirteen. The example code has it defined equally pin 11 in the hookup table. Make sure to check your pivot definition for the clock as it may vary with the code yous are using.

Connecting to A, B, C, (D for 32x32 users), OE, and STB Pins

These five (or 6 if you're using a 32x32 matrix) pins can be plugged in anywhere you may take infinite on your Arduino. Although, there's probably not a lot of room left... We chose to stick A, B, and C in pins A0, A1, and A2 respectively. OE connects to pin 9. STB to pin 10. And, if you're using a 32x32 matrix, D goes to A3 equally stated in the hookup table.

Feel free to swap those upwardly if your awarding requires. Just brand sure you switch it up in the example code too.

Connecting to Ground(s) Pins

Terminal, but certainly not least (well, maybe, if we're talking about potential) is ground. At that place are three unlabeled pins on the connector which should all be tied to ground.

If you don't have anything else plugged into them, at that place should exist three footing pins available on your Arduino. If you're struggling to notice ground pins, though, you lot should exist able to get away with just plugging i of the ground pins to your Arduino. Woo color coded wires!

Power

Once you are finished connecting the LED panel to an Arduino, add together your 5V power supply to the console's power connector. Don't forget to add power to your Arduino!

Connecting to 32x64 RGB LED Panels

For anyone connecting to the 32x64 RGB Panels, y'all volition demand to use an Arduino Mega 2560 with the library. Otherwise, the panels volition not be able to brandish as expected due to the limitations of the library and the Arduino Uno.

To daisy concatenation two 32x32 RGB matrices together, connect another IDC cable from the output of the first panel to the input of the second console. Then connect the second 4-pin polarized connector to the input ability connector. After modifying the test_shapes_32x64.ino, the display will output equally a 32x64 matrix as shown below.

Here's an case with the 32x64 matrix with 4mm pitch.

When using an array higher than 32x64, some other library would exist a better option with a Teensy 3.0+, FPGA, or Raspberry Pi. You may need to level shift to convert 3.3V to 5V for the RGB LED panel to recognize the I/O signals. For more than data, check out the links in the Resources and Going Further.

Custom Shield Adapter

If you have a prototyping shield, endeavor making a custom shield adapter for a more than secure connexion. Here's an example of using an XBee shield'south prototyping area with the connection specifically for the RGB LED panels. Follow the steps outlined above but solder the connectedness together.

Magnetic Mounts

Depending on the supplier, you may receive a set of magnetic mounts. Add together information technology to the console'southward mounting holes to stick on a fridge or metal wall! They also work great as a standoff. Just make certain to secure and insulate your wires to forestall whatever shorts if in that location is metallic backside the panel.

Arduino Library Installation

Note: This example assumes you are using the latest version of the Arduino IDE on your desktop. If this is your start time using Arduino, please review our tutorial on installing the Arduino IDE. If you lot have not previously installed an Arduino library, please check out our installation guide.

Compatibility: The 16x32 works at a 1:8 scan rate. The 32x32 and 32x64 examples piece of work with a 1:sixteen browse rate. Depending on the manufacturer, there may be unlike scan rates for the the LED Matrix Panels. Using unlike browse rates with the case code may cause unexpected behaviors.

Our example lawmaking is going to make utilise of Adafruit's most excellent RGBMatrixPanel library, which as well requires their AdafruitGFXLibrary. You can obtain these libraries through the Arduino Library Director by searching for those names. Or you tin manually install them can by grabbing both of them [RGBMatrixPanel and AdafruitGFXLibrary] from their GitHub repositories.

For your convenience, we packaged those libraries with the serial pigment example code used in the tutorial:

Library Examples

The RGBMatrixPanel library includes a number of fun examples to help prove how the library can be used. They're awesome. Bank check them out under the File_ > Examples > _RGBMatrixPanel menu in Arduino. (Definitely check out the Plasma_16x32 or Plasma_32x32 examples!). Make certain to adjust the lawmaking based on your hardware hookup. In this tutorial, we physically continued the clock pivot to 11. Therefore, you need to adjust the divers CLK pivot from

            language:c // If your 32x32 matrix has the SINGLE HEADER input, // utilise this pinout: #ascertain CLK viii  // MUST be on PORTB! (Employ pin 11 on Mega) #define OE  9 #define LAT 10 #define A   A0 #define B   A1 #define C   A2 #define D   A3                      

to:

            language:c // If your 32x32 matrix has the SINGLE HEADER input, // use this pinout: #ascertain CLK 11  // MUST be on PORTB! (Use pin eleven on Mega) <---CHANGE! #define OE  nine #define LAT 10 #define A   A0 #define B   A1 #ascertain C   A2 #define D   A3                      

Example Code

Series Pigment

We wanted to write some other fun sketch that provided an interactive style to explore with the panels and the Arduino library. What we came up with is a serial-controlled paint program. With this sketch, y'all can use the serial monitor (or, better yet, another terminal program) to control a cursor and draw on the matrix.

Download and unzip the sketch included in the zipped libraries using the link below if you have not already.

• Selecting You LED Matrix Size

Earlier uploading, make certain the sketch is fix to work with your panel where it says:

            language:c /* - One of these should exist commented out!    - Also, make certain to arrange the saved image in the <bitmap.h> file.*/  /* ========== For 32x64 LED panels: ==========   You lot MUST use an Arduino Mega2560 with 32x64 size RGB Panel */ //RGBmatrixPanel matrix(A, B, C, D, CLK, LAT, OE, false, 64); // 32x64  /* ========== For 32x32 LED panels: ========== */ RGBmatrixPanel matrix(A, B, C, D, CLK, LAT, OE, false); // 32x32  /* ==========  For 32x16 LED panels: ========== */ //RGBmatrixPanel matrix(A, B, C, CLK, LAT, OE, false); // 32x16                      

By default, the Serial Paint example uses the 32x32. If you lot are using 32x64, brand certain to uncomment the following line by removing the "//"

            language:c //RGBmatrixPanel matrix(A, B, C, D, CLK, LAT, OE, fake, 64); // 32x64                      

And then comment out the following line past calculation a "//" at the beginning of the line.

            language:c RGBmatrixPanel matrix(A, B, C, D, CLK, LAT, OE, false); // 32x32                      

• Selecting the Saved Bitmap Image

Make certain to too uncomment/comment out the bmp[] assortment in the bitmap.h file by removing and adding "/*" and "*/" for your respective size.

• Upload!

In one case you take adjusted the code to your screen, upload it to the Arduino! Afterward upload, a single pixel should be blinking at the top left of the panel. It doesn't look similar much, just that'due south a skilful sign.

Using the Sketch

To control the plan, open up up your series final to 9600 bps. Endeavour hitting sending l (lowercase '50') through the serial monitor, which should load the demo bitmap. Y'all can transport E (capital letter) to erase the screen.

The idea of this sketch is: move the cursor around to draw pixels, shapes, or text. Here are the commands made available by the sketch (they are instance-sensitive):

• Move: w, a, due south, d (up, down, left, right)
• Draw Pixel: Spacebar
• Erase Pixel: e
• Erase Screen: E
• Fill screen with active color: f
• Colour Control:
  • Red value up: R (values between 0 [off] and 7 [about bright])
  • Red value downwards: r
  • Green up/downwardly: Yard/one thousand
  • Blue up/downward: B/b
  • Re-create color: z (copies a color nether the cursor)
• Shape Cartoon:
  • Line: press v to place starting point. So move cursor to endpoint and press v once again.
  • Rectangle: printing ten or 10 to identify first corner. Then move your cursor to where yous want the diagonal corner. So press either x for an empty box, or X for a filled box.
  • Circle: press c or C to place the middle of the circle. And then move your cursor to where you want the outside edge of your circle to exist. Then press c for an empty circle or C for a filled circle.
• Text: press t to go to text mode. Now any characters received volition be displayed on the panel. It'll wrap around from ane line to the adjacent, only not from bottom to top. Press ` (above Tab / left of 1) to go out text mode.
• Print: press p to print an array of your cartoon to the serial terminal. You can re-create this, and put information technology back in your sketch if you desire to load information technology again.
• Load: printing fifty to load a pre-defined assortment from the sketch. The sketch includes a demo assortment, which was created from the print command. Follow this example to load your ain drawings!

Give the pigment sketch a attempt! See if y'all can make the next swell Calorie-free-Brite LED Console picture. If yous make something neat, share it with u.s.a.! Don't laugh. I drew that SFE flame one pixel at a time! Hither are our creations:
