## 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.

## The case and keycaps

The case is 3D-printed (PLA Basic), and every printed part comes in a choice of colours: black, white, gray, red, yellow, blue and orange. The "Case" group in the parts list holds:

- Front and rear shells
- The screen bezel
- 3 keycaps (they fit on the mechanical switches)
- 1 joystick cap and 1 joystick spacer

Each part is preselected in its default colour on the page; change it to the colour you want.

## The screen

Choose a non-touch or touch version of the 2.8-inch 480×640 IPS MIPI-DSI display. The touch version is selected by default.

The touch version includes a matching front case and does not need a screen bezel. Choosing it does not automatically change the front case or screen bezel quantities in the parts list.
