Build

1. Cut free the two sides of the board.

Figure: PCB plate.

1. Add switches to the corners of the switch plate.

Figure: Switches in the corners of the switch plate.

1. Attach the PCB to the switch plate ensure that the switch prongs line up and do not bend. Once done, finish adding the rest of the switches in via the switch plate. Do not add keycaps on until a later stage as they make screwing the bottom plate in difficult.

1. Screw in the spacers to the bottom plate. Ensure not to tighter too much as this can damage the PCB and/or spacers.

Firmware

Download the firmware for VIA/Vial.

• VIA - crkbd_rev4_0_standard_via.uf2

• Vial - crkbd_rev4_0_standard_vial.uf2

Perform the following steps for both sides of the keyboard.

1. Connect the side of the keyboard you intend to flash to the computer while holding down the BOOT button. If you're already plugged in to the computer, you can instead hold the BOOT button followed by the RESET button. This will mount the micro-controller.

Figure: Location of the RESET and BOOT buttons.

1. Drag the downloaded .uf2 file from above onto the mounted device. This will flash the firmware onto the micro-controller.
