Interstate 75 W is a RP2350-based driver board for HUB75-style LED matrices - they're the chainable LED panels that you sometimes see making up video walls or big advertising displays. It's designed to plug neatly into the back of a LED panel, and it provides a quick and easy way to whip up some scrolling signage or an eye-catching LED display for sensor outputs. I75 W has wireless connectivity so you can also use it to display information from the internet!
