Soldering

Solder the switch sockets and RP2040-Tiny to the main PCB.

Soldering the Switch Sockets

1. Apply solder to one of the pads for each switch socket in advance.

Caution

The pre-installed LEDs on the main PCB are heat-sensitive, so take care not to overheat them while soldering.

2. Fit each switch socket onto the PCB, aligning it with the orientation shown by the silkscreen.

Caution

The orientation of Kailh Choc switch sockets can be confusing, so check it carefully before soldering.

3. Hold the socket down with tweezers and melt the solder on that pad again to secure it.

4. Solder the other pad to secure the socket.

5. Repeat these steps for all switch sockets.

Soldering the RP2040-Tiny

1. Position the RP2040-Tiny on the pads provided for it on the main PCB.

2. Apply flux to the pads and castellated through-holes.

3. Solder each pad, one at a time, to secure the RP2040-Tiny.

Information

To make soldering the first pad easier, hold the RP2040-Tiny in place with masking tape or similar.
