Arduino®CompatibleLEDCreate dazzling LED displays with this RGB LED Matrix Shield that simply plugs directly onto your UNO compatible board. The built-in driver IC and 12V programmable constant current circuitry ensure each LED can reach full brightness and colour. The data transfer protocol uses single NZR communication mode. After the pixel power-on reset, the DI port receives data from controller. The first pixel collects initial 24-bit data then sends it to the internal data latch
