Assembly

Install the switches and keycaps on the top case and main PCB, then mount the USB port adapter on the bottom case.

Installing the Switches and Keycaps

1. Place the main PCB against the underside of the top case, align the parts, and insert a switch at each corner.

2. Insert the remaining switches in the same way.

3. Install the keycaps on the switches.

Installing the USB Port Adapter

1. Position the USB port adapter against the posts on the bottom case.

2. Secure it with the pan-head screws (M2 × 3 mm).

3. Connect the RP2040-Tiny on the main PCB to the USB port adapter with the included FPC cable.

Caution

With the connector cover open, check the FPC cable orientation and insert it straight in as far as it will go.
After that, make sure the cover closes fully without force.

For details, see the Cable Connection section of the Waveshare Wiki.

Information

Leave the top and bottom cases unsecured for now; you will need to press the button on the USB port adapter when flashing the firmware.
