iiunius 64x64 RGB LED Matrix Panel Full Color voor Raspberry Pi/Ardui 192x192 mm 3mm Pitch 4096 LEDs Verstelbare Helderheid

In case anyone is wondering. These are WLED compatible on WLED MoonModules using an esp32. I’ve hooked everything up directly to the esp32 and it was a fairly simple plug n play. WLED MM does have a limit on chaining matrix however.

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'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.
