Enter the (LED) matrix with this all-in-one, USB-C powered controller for HUB75 panels.

Interstate 75 is an RP2040-based driver board for HUB75-style LED matrices. It's designed to plug neatly into the back of an 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 64x64 (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 are also two useful buttons, a reset button and an onboard RGB LED.

Pimoroni also popped a QW/ST connector on there, to make it super easy to plug in Qwiic or STEMMA QT breakouts.
