Meet Quadra: A $35 Complete Mini-PC for Amateur Radio (and more!)

Update: Now includes popular ham radio apps pre-installed. HamClock, WSJT-X, js8call, GridTracker, Pat (Winlink), and the flDigi suite are all ready to use out of the box, plus an installer to add more easily.

Not just a raw board, Quadra is a complete modern Linux computer that can be used as a server or light-use desktop. It includes the case, heatsink, power adapter and HDMI cable. Just plug into a TV or monitor and a keyboard/mouse. No SD card needed as the OS (Debian Bullseye 64-bit) is pre-flashed in internal memory. A great option instead of Raspberry Pi when you don't need the 40-pin I/O header or want something more affordable that doesn't require assembly.
