Adafruit RGB Matrix Shield for Arduino

Our RGB arrays are dazzling, with their hundreds or even thousands of individual RGB LEDs. Compared to NeoPixels, they have high density, power consumption and price per LED that cannot be beaten. But...(isn't there always one but?) You need to use our special library to control them and they need a bunch of wires to be connected. More robust than a single-wire connection, that's for sure.
If you have an Arduino compatible card, with an ATmega328p chip (like our Metro 328) or SAMD21 (like the Metro M0) or even SAMD51 (like our Metro M4), this shield will make using it child's play! A little light solder to fix the connector, die connector and terminal block and you are ready to go. Plug it into your microcontroller card, and you can easily connect any RGB matrix. This shield only takes care of the wiring for you!
For a power consumption of 800mA or less on the matrix, you can even "borrow" the 5V power from the Arduino regulator. This is not good for projects where you have many LEDs lit at the same time, but for text scrolling and using LEDs, it will make wiring even easier because you don't need a separate power adapter. Of course, if you need 1 Amp or more, just use the 2x8 connector for data and use a 5V 2A or 5V 4A power supply directly on the board.
Note that this shied is only a cable adapter, if you have a Metro 328, you can only use 16x32 or maybe 32x32 matrices before running out of RAM. For large panels, use a Metro M0 or M4 - these will work better thanks to their huge RAM.
Please note that our Arduino library only supports 32 pixel high arrays, so do not try to use a 64x64 array, it does not work!
