Just got it powered up and running under MicroPython using a Raspberry Pi Pico. It required five wires to connect to the microcontroller, and an additional line to 3.3V to power the backlight. I used a 470 ohm resistor on the backlight line, but you can do a direct to 3.3V line for full brightness or use a pot for variable brightness.
There is a helpful tutorial with links to code at https://blog.0x32.co.uk/posts/pico8/ Note that the pinout in the tutorial is in a different order than on our board and the “A0/DC” line on their board is the “RS” pin on our board.
Pretty cool to get a “big” RGB display at this price! 🙂
