64x64 RGB LED Matrix Panel Full Color for Raspberry Pi/Ardui 192x192 mm 3mm Pitch 4096 LEDs Adjustable Brightness

This 64x64 panel is almost plug-and-play with the MatrixPortal. There are three things you must do to get it working in an Arduino environment: 1. Add a solder blob for Pin 8 for the Address E Line Jumper on the MatrixPortal board. 2. Assure that the address pins array reads like this: uint8_t addrPins[] = {17, 18, 19, 20, 21}; (The "21" is in the example sketches, but it's not present in the "simple" example described in the "Adafruit MatrixPortal M4" guide, as of 12 December 2024.) 3. When creating the Protomatter object, the number of row-select address lines should be "5". The configuration should read: (64, 4, 1, rgbPins, 5, addrPins, clockPin, latchPin, oePin, false);

I have 20 of these bad boys interconnected with a custom emulator. Now I can play Pac-Man on a 65k LED display, the way god intended.

I ordered these as they looked the same as some panels I had purchased before. I thought there was a picture of the back of the panel when I purchased them, but don't see it now. The back, including connector placements is different from others! My design was around the different back panel, so I had to do some hacking to get things to fit. Also, timing seems a bit different compared to before. I had to slow down the pixel clock to get cascading to work. Not a big deal as it is a DIY project and I have full control over all aspects. Main thing is just be aware if you got some other panels, these could be a bit different.

I'd hoped to wire mine up before review deadline, but real life intervened. The physical panel is rigid and not bendy. The provided magnetic/screws would make this easy to mount into a frame. Before this panel, I was unfamiliar with HUB75 but spent a lot of time studying the electrical and signaling protocol and other projects in this ecosystem. The interface is well documented (start at GitHub, of course) and there are provided cables both for connecting this to a micro that provides 5V TTL interface (which are pretty rare these days) as well as a 'downstream' cable that allows you to chain many of these together, just chaining the device latch strobes. Several companies like Adafruit offer interface boards that handle the 3.3V from your tiny SBC (Pi, Pine64, Star64, VisionFive, etc.) to the 5V that this device claims to need. Those "hats" or "shields" can also help shave off some of the ugly timing requirements if you're trying to feed a large quantity of these in an animated motion, panning, or scrolling. The business end of these seems to be D7258 that drives a bunch of blinkies from a low number of signals, while also handling ghosting and allowing a refresh rate beyond what you could get with just a few data bits and a strobe. Apparently, it's common wisdom with these that if you're planning a project that'll need a few of them, that you should buy the panels from the same company and try to get them matched from the same batch/datecode so that the color calibration will match. I'm granting it five stars for containing exactly what it said it'd contain, being a reasonable value when compared to comparable products on Amazon, and whetting a curiosity on how I'll control one of these (can I do it with only 3.3V outputs? Can I do it from a BluePill class CPU? Can I put one on the wall as an animated clock, perhaps feeding data from MQTT to remind us when it's late and the EV needs charged overnight?) I'm looking forward to playing with this panel more and may come back to this review with pictures of my creation later.

This 64x64 board is half the price of one of the most popular sites online. I think it's great that they give us the ribbon cable fitted with wire jumpers, but it took me 2 hours to map the jumpers to the standard 40-pin pi pinout (of course, I was labeling the graphics at the same time). In photo 1, I've added to a popular git repo with the colors and specifics for this board. Note that "LAT" on this board is what others call strobe. Also note that I took advantage of ground pins that were closer to the rest of the ribbon sequence, whereas the wiring table on made use of pin 6 ground (pi has more grounds, so use them!) Photo 2 is the odd-number pins of the pi header (1-39), 1 on the far left. Photo 3 is the even-number pins of the pi header (2-40), 2 on the far right. I hope this saves you some time, and saves the expense of buying a pi hat/header. This board is a great price, and opens a lot of creative possibilities!

Well, this was a learning experience. I'm not a hardware guy, so I got this expecting to use it like I have with smaller matrices in the past. Turns out that is not the case. I should have realized that it would be different controlling 4096 LEDs. First of all, there are a lot more wires to connect. I hope you like soldering. I'm awful at it because my hands shake, and my eyes aren't the best. There are hats/shields you can buy, but all the ones I have found also require soldering. Just not as much of it. Also, this requires a lot more power. It's 4096 LEDs after all. Make sure you have a good power supply. I'd suggest 5 amp minimum. And it also takes more processing power and memory. The panel isn't that smart, so you have to constantly refresh it in order to keep a display going. I was hoping to use my ESP32 for this, but I won’t be able to. There are some cool GitHub projects, but they either require certain ESP32 models or are more limited than I would like. I winded up connecting it to a Raspberry Pi. Adafruit's tutorials were invaluable for this BTW! And it works great. The panel looks amazing and is just what I needed for my project. I just don't know that I want to dedicate a Pi4 to it. Raspberry Pi devices are so hard to get and expensive right now.

Funktioniert einwandfrei und auf Anhieb, ohne großartige Bastelei oder Gepfriemel zusammen mit dem Adafruit Matrix Portal ESP32-S3 Modul und der Protomatter Bibliothek in der Arduino IDE. Die Sand Demo läuft geschmeidig. Einzige Modifikation im Code: HEIGHT auf 64 setzen. Tipp: Das Board als 'Adafruit MatrixPortal ESP32-S3' verwenden, als generisches 'ESP32-S3 Dev Module' streikt es beim Upload. Über das Panel selbst gibts nicht viel zu sagen. Leuchtstark, brilliant, bunt!
