What is it?

This shield is for easily controlling RGB LED Matrix panels using with a Mini 32 ESP32 board ,aka the ESP32 D1 Mini.

Assembly Required: This shield is a kit, but uses all through hole parts so is easily assembled.

It is designed to work with the ESP32-RGB64x32MatrixPanel-I2S-DMA library. It will not work with PxMatrix library! Use this board if you want to use PxMatrix.

NOTE: This board will only work with Matrix displays that the I2S library supports. Please check out the libraries' Github page for more information.

Why did you make it?

The RGB LED matrix panels are one of the coolest displays you can use with an Arduino, but there is quite a bit of wiring to connect them up and also they are a little awkward to power. The panels are only about $20 from aliexpress/eBay

This board makes wiring them really simple! The board just slots directly onto the input header pin and has screw terminals to connect the power cable that comes with most panels.

Unlike previous matrix panels I sell, this design does not require to connect to the P-Out connector using the ribbon. It should also be better able to handle connecting to multiple displays. It is also much more performant than the previous version.

What makes it special?

This really makes using the display as simple as possible and can be used to make some pretty awesome looking projects!

It also has pins broken out for GY521 (MPU6050) accelerometer module so you can make some pretty interesting falling sand projects with it!

Examples sketches for using these displays.

The ESP32-RGB64x32MatrixPanel-I2S-DMA library comes with some pretty cool examples. I really recommend checking out PatternPlasma and AuroraDemo

Note: These displays are difficult to video correctly, they look much better in person!

Aurora - Click here for larger

What is included?

Each ESP32 I2S Matrix Shield is a kit and comes with the following:

ESP32 I2S Matrix Shield PCB
220uF 25V Capacitor
220k resistor for discharging the Cap
Schottky Diode (1N5817)
3 male pin headers
1 Jumper block
16 pin female header (2x8)
Large Green screw terminals
2 x standard screw terminals (one red and one black)

What is NOT included?

The following components are not provided, but are required to use this board.

Mini 32 ESP32 Board - These can be bought on Aliexpress/Ebay for around $5. The Add-ons listed here have all been tested and come with 4x10p Male and Female Header pins.
Compatible HUB75 RGB LED Matrix Panel
Most (all?) panels come with a power cable, this board requires this.
A 5V PSU cable of running the display (roughly 5A for a 64x32 model). The barrel jack is standard 2.1mm Jack, but you can also use the optional screw terminals to power the board.

Will it work with my display?

I can't answer that for sure, it should work with any display that works with the ESP32-RGB64x32MatrixPanel-I2S-DMA library. I can't guarantee that all display's will work.

If you are looking for installation instructions or more information about the board, please checkout the boards Github page.

Coding Support

Please note that I can not provide coding support for this item. I can offer some troubleshooting advice on getting them working (but please also read the section labeled "will this work with my display") and I can point you to some examples I have created using these board, but I will not be able to give support on building something specific.

This board great. Quick shipping too.

This board is great. I am driving an led matrix with it. It's well thought out all the plugs are in the right places and its been simple to get it setup and going. Shipping was quick too. I will buy these again.

ESP32 I2S Matrix Shield

Works like a charm. Thanks brian!! No more loose cables. It even works with the RGBmatrixPanel library (Some tinkering needed!)

Adrien | March 9, 2021

Amazing little LED matrix shield. Easy to assemble.

It is a great little LED matrix shield that is easy to assemble (thanks to through hole components) and neatly designed. It was up and running in 20 minutes. Documentation is great and sample projects are really cool (I need to understand better some of the sample projects code though). I am no developper at all, just a graphic designer with some soldering skills.
Brian and Caroline packaged the board neatly and sent it really fast.
Great stuff, keep up the good work! :¬)

Cool Product

I'm having lots of fun with this shield, easy to use, and also easy to assembling.
east to install at the of back panel.

Plug and Play for HUB75 and HUB75E modules

After struggling with unreliable manual breadboard wiring, I caved and bought these boards.
Works flawlessly and let me focus my energy on programming instead.
Make sure to read the instructions, I missed a step and got confused for a moment.

Examples are a great jumping off point for your own projects.

Fast and efficient shipping to the USA, and great customer service.

the shield dont work

Ich habe das shield nach der Anleitung zusammengebaut, und mit dem ESp 32 programmiert , aber nicht funktioniert keine LED leuchtet

Response from Brian Lough | Sept. 29, 2020

Hi Matthias

Sorry that you are having problems, but you could have contacted me to get support and I could have at least tried to help. The board will only support whatever displays work with the I2S matrix library though

Es tut mir leid, dass Sie Probleme haben, aber Sie hätten mich kontaktieren können, um Unterstützung zu erhalten, und ich hätte zumindest versuchen können, zu helfen. Die Karte unterstützt jedoch nur die Anzeigen, die mit der I2S Matrix library funktionieren (Google translate)

Great product from Brian, as usual!

I have numerous panels from Ali-Express and they all work fine with this board. The SPI library is so much faster than PXMatrix.

Response from Brian Lough | Sept. 29, 2020

Thanks Owen! Glad it worked out for you.

Nigel | Sept. 3, 2020

A fantastic shield

Another great product from Brian. It makes setting up the matrix panels a breeze. I just wish the programming would come as easy for me. A little tweak here and there and its up and running. Great documentation and help along with some great libraries that he and fellow programmers are involved with.

Response from Brian Lough | Sept. 29, 2020

Thanks Nigel. I'm working on some projects for the i2s matrix I think you'll really like, so stay tuned!

Makes the i2s connection a breeze

When I saw the i2s dma library in a test video, I just knew it was the way to go. I was originally going to get his other board but he had just released this one and I'm glad I got this one instead. The shipping from Ireland to Florida only took a week or two. The instructions were very clear. Make sure you use a lot of solder on the screw terminal. The only change I would make would be to use a male IDC (2x8) connector (like the one on the led panel) so I could use the included ribbon cable that comes with every led panel. It creates a more secure connection. My led panel has a frame on the back that doesn't allow Brian's board to seat properly, so I use a female to male ribbon cable.

Response from Brian Lough | Sept. 29, 2020

Thanks Patrick. Thanks for the feedback around the male IDC connector, I will hopefully add that as an add-on in the future. One of the problems with these matrix panels is they come in all flavors and sizes! The board fits all mine ok, but I understand there are ones that it doesn't.

Great little board

Really crunches down the size of device needed to drive a HUB75 LED array well, Up and running quickly, a little too quickly for me as I beat the docs going up, but lots of help on the Discord server and I have much glowyness to hand.
