## 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.
