I have a product question. I am interested in using the Pimoroni Hyperpixel 4 square screen.
I know it covers/uses all the GPIO pins.
Is it possible to connect another RPI so that I can use the GPIO pins from the other Pi? (Use the other Pi as a ‘slave’?)
I’m building a speaker / retro game box and need a way to connect an power status LED, a shutdown momentary switch and maybe a fan. I hope this question isn’t too confusing. I did a little bit of googling but I may not be using the correct group of words to find the answer myself.
Thanks for any help,
