Interstate 75 is a?RP2040-based driver board for HUB75-style LED matrices. It’s designed to plug neatly into the back of a LED panel, and provides a quick and easy way to whip up some scrolling signage or an eye-catching LED display for sensor outputs.
I75 is?powered and programmable by USB-C.?USB-C is capable of providing up to 3A of power which should be enough to power a single 64×64 (or smaller) panel, assuming you’re not planning anything too eye-bleedingly bright. If you need more power than that (so you can chain multiple panels together, perhaps?) you can inject it into the screw terminals instead. There’s also two?useful buttons, a reset button and an?onboard RGB LED.
