Such an awesome computer to build. Thanks for sharing the project and the BOM!
Built mine with Intel stick PC running Debian with awesomewm. Powered by 16Ah LiFePO4 battery for extra long service life. Added modules to boost the battery voltage to 5V, and added 5V + 12V inputs, so the computer will run (and charge) on both 5V or 12-36V inputs, or the battery. Also added a small voltage meter so battery soc can be monitored. Charging module is set to ~3.33V, so battery is never overcharged. Found a nice 8.9" 500 nits ips display that only draws ~350mA. Also added mechanical on/off switches to turn on/off display, charging module or completely disconnect the battery from everything.
Still a WIP. Waiting on smaller/flat HDMI cable to make room for more USB ports to add GPS and LTE modules. Only got 1 free USB port now.
Went with https://github.com/SalmonChris/KeyboardMouse for mouse control after making some edits to it (WASD + cursor movement and extra button keys).
