Please note: Pic is for illustration purposes only. The frame on the rear of the panels might be shaped differently.
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. They have bright RGB LEDs arranged in a 32x32, 32x64 or 64x64 grid on the front. 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.
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.
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. Instead, you're supposed to redraw the screen over and over to 'manually' PWM the whole thing. 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). They are pre-white balanced with nice uniformity so if you turn on all the LEDs it's not a particularly tinted white.
Here are some nice, tidy ways to connect up and drive your LED matrices:
- Interstate 75 (RP2040 based all-in-one controller)
- RGB Matrix Shield (for Arduino and compatibles)
- RGB Matrix Bonnet or RGB Matrix HAT (for Raspberry Pi)
- RGB Matrix Featherwing (for M0, M4 and RP2040 Feathers or nRF52840 Feathers)
