On a 16 MHz Arduino, it's possible to squeeze 12-bit color (4096 colors) with 40% CPU usage but they will do best powered by an FPGA or other high speed multi-core controller (like a recent Raspberry Pi or Feather). Instead, you're supposed to redraw the screen over and over to 'manually' PWM the whole thing. These displays are designed to be driven by FPGAs or other high speed processors: they do not have built in PWM control of any kind. These panels require 13 digital pins (6 bit data, 7 bit control) and a good 5V supply, up to 4A per panel). They are 'chainable' if you connect one output to the next input - you will need a microcontroller with a suitably high speed processor and enough RAM plus a software library that supports this. On the back there is a PCB with a set of dual IDC connectors (one input, one output) and 12 16-bit latches that allow you to drive the display with a 1:16 scan rate. They have bright RGB LEDs arranged in a 32x32, 32圆4 or 64圆4 grid on the front. These HUB75 style panels are normally used to make video walls, you can sometimes see them on the sides of buses and bus stops displaying animations or short video clips. Bring a little bit of Times Square into your home with these sweet RGB LED matrix panels. ![]()
