AZERONE Pixel led Panels Digital led Module Indoor led Display Screen RGB Matrix led Board (P3-192 * 96mm)

Works great with an arduino mega! For anyone else who wants to, search the following in your favorite search engine, you should find a direct link to this file: "32x16-32x32-rgb-led-matrix.pdf"Be sure to pick up a reliable 5v power supply that can do 5 amps. These LED's suck power.Here's how I hooked it up to an Arduino Mega. (Starting as Top Left being #1, Top Right being #2 --- Top is the orientation if the unit is sitting with the painted arrows UP).1 - 242 - 253 - 264 - Ground5 - 276 - 287 - 298 - Ground9 - A010 - A111 - A212 - A313 - D1014 - D915 - D1116 - GroundBe sure to define the variables properly per that guide, and ensure you have the wiring correct. If you're using a regular arduino, that guide has it written in plain english how to hook it up. The only other thing you need to do is use the , 64 overload on the RGB_Matrix library.

I have this board hooked up to the adafruit hat, and it displays the info I was hoping. I have it hooked up for an MLB home scoreboard, and it displays very nicely. It sometimes slightly flashes once in a while, but I didn't solder the jumpers to try to remedy the issue. It's not an issue for me since I'm not staring at it constantly. I was skeptical at this price, but have been pleasantly surprised and wouldn't hesitate to purchase another if I needed one.

I received a P3 64x32 display early Jan. 2019 with new driver chips, FM6126A instead of the older FM6124 chips. This wouldn't matter but currently no existing libraries I know of accommodate this new driver chip. This means the display appears broken until the library you use is updated. The creator of the PxMatrix Arduino library 2dom is currently working on updating his library for these new panels. You can see the discussion at the GitHub page for pxmatrix issue#52. I would put the link here but then Amazon won't post my review...I am giving 3 stars for now and will update when I can test the display with updated code

I bought eight of these. Of those eight, one works fine, one lights up but is cracked, and six are completely dead. See details below.I originally bought one of these 32x64 displays. It came with an orange "180890-01 M0771" sticker on its back. I hooked it up to my Raspberry Pi and after a bit of troubleshooting (on the raspberry pi side), it worked perfectly.I then decided it would be safe to buy another three of the exact same displays. Of those three, two were completely dead and one was cracked showed glitched light patterns only.I was upset and initiated an Amazon return for those three faulty displays. Since I still owned one working display, I decided to give this company another shot. This time I ordered four displays, thinking that perhaps one will be dead on arrival (and I could return that dead one without further delaying my project). Unfortunately, all four of those displays are dead on arrival!!To be clear, all of the displays are completely identical to the one I originally ordered except for the stickers on the back (which I assume indicate their date of manufacture and lot number). I am testing all of the displays in a consistent way, in which my original one works and all others do not work.I am open to suggestions of what I might be doing wrong - but I am personally convinced that these are faulty displays. I've done a lot of troubleshooting. Maybe they recently had a few bad manufacturing lots? If that's the case, they should probably notify buyers. I'm not happy that I've spent $175 on faulty displays so far. But I am really upset that this has delayed my project severely. I've also wasted a ton of time troubleshooting broken products. Not fun. I will probably not turn to Amazon next time I need a reliable electronic product like this.

I got two of these panels, and they work great. The biggest issue with these, and anywhere else you happen to find them, is the documentation for them is basically non-existent. You will be completely on your own for figuring out how to interface with them, or you can use libraries made by someone else. I've successfully used the Smartmatrix library with two of these panels connected in series to make a 128x32 pixel panel. Quite a lot of libraries I found could not handle a display this size, for example, Adafruit.If you want to make larger panels you're going to need FPGAs. The way the pixels are written is done serially so if you want a decent refresh rate you need to write to additional panels in parallel rather than connecting them in series. It just takes too much time to shift out all those bits. Most microprocessors, especially Arduinos, won't be able to handle that.The data connection is HUB75, but again the specifications for that are not published anywhere. At least anywhere I could find. They are capable of 24-bit color (8-bit red, 8-bit green, and 8-bit blue). There are 2 pins for each color (R1, R2, G1, G2, B1, B2), then four address pins, the clock, a latch pin, and then an output enable. 4 address bits = 16 combinations. So with 2 pins for each color, you get your 32 rows.So if you know what you're doing, or if you're looking for a learning project, these are a great inexpensive panel. If you know nothing, don't want to know, and are looking for a "plug and play" solution ... you probably won't want to go with these.
