What to do when it arrives

The development board comes with its headers already soldered. Use the female headers in the kit to join it to the custom baseboard.
The parts on the baseboard need soldering. If you would rather not do it yourself, add the “Board soldering” service and we do it for you.
The case is 3D-printed. It is assembled with screws and heat-set brass nuts.

What the case includes

“Complete case (3D-printed)” in the parts list is one full set of printed parts, not listed piece by piece:

Front and rear shells
3 printed keycaps (they fit on the mechanical switches)
1 joystick cap

The screen

The screen in the kit is a 2.8-inch MIPI-DSI module without touch.
