Description: Are you looking to add a lot of color to your project? These large 32x16 RGB LED panels are an awesome place to start. You can create animations, games, or all sorts of other fun displays with them. Yes, you read that right: a 32x16 LED matrix, that's 512 LEDs on a 7.5" x 3.75" board. On top of all that, thanks to two IDC connectors, and a seamless frame, these panels can be daisy chained together to form even bigger LED displays. 

These panels require a regulated 3.3-5V supply for power which needs to be able to source a good amount of current – up to 2A in the worst case. Included with each panel is a 0.15" pitch 4-pin polarized connector power cable which is terminated with both a female polarized connector, and a pair of spade terminals. Needless to say, if you are looking for a large, cheap, and easy to use RGB LED matrix you've come to the right place. 

Note: These displays were intended for use with FPGAs and high-speed processors. We've found that 16MHz is about the slowest processor that can drive these adequately. If you want to daisy-chain them together, you will need more speed and more RAM.


  • 512 RGB LEDs

  • I’m working on a library for the Teensy 3.1 to drive these panels using DMA. I have an early version that’s able to produce 24-bit color with low CPU usage. I expect to have the library along with an Open Hardware adapter board released in about a month. If you’re buying one of these panels I suggest you pick up a Teensy 3.1 over an AVR-based Arduino to drive them, the Teensy 3.1 is much more capable.

    I’m posting on my project here:

  • The labeling on this panel for the Input connector is behind the frame and impossible to see. Also the labeling that is visible (on the right hand side of the connector) starts on a 1 based system (ie: G1, G2) While the hookup guide shows a 0 based (G0, G1). This should be corrected to avoid confusion

  • Do you know which LED video wall drivers this matrix is compatible with? For instance, how about the one at adafruit:

  • BEWARE: The pins used in the Adafruit library are NOT the same as the ones used in the Hookup Guide. In particular pay attention to the clock and latch pins.

    This is extremely bright (will hurt your eyes!). One thing that helped me while developing was placing a thick paper napkin over the panel like a diffuser. This not only lowers the brightness a lot but also makes it diffuse enough so that you don’t see the pixels.

  • Can an Arduino Pro mini run this? If not how about a regular Arduino Pro? The Arduino would not be doing much… It would just be acting as a alarm clock.

  • I wonder if it is possible to reduce the common brightness. I tried to understand what’s happening in the timer interrupt (RGBmatrixPanel.cpp), but I did not succeed. Do I have to trial and error, or has someone a solution for me?

  • These are very nice panels. Used one in a game of life clock i built: very bright and hard to look at without something diffusing the display.

  • What is the maximum clock rate for the shift registers?

  • Is it safe to assume the Teensy 3.1 could handle driving this?

    • Just got done coding on the Teensy 3.1. You cant use the RGBmatrixPanel library, so I made my own. Check it out here: ‎

  • Datasheet please?

    • we don’t have one, neither does the manufacturer. hopefully the hookup guide helps you out a bit.
