Adafruit Feather RP2040 with DVI Output Port - Works with HDMI

Wouldn't it be cool if you could display images and graphics from a microcontroller directly to an HDMI monitor or television? We think so! So we designed this RP2040 Feather that has a digital video output (a.k.a DVI) that will work with any HDMI monitor or display.
