Building the Device

Prepare the Components

Gather all your parts: XIAO board, battery, switch, wires, and 3D printed case.

Cut the Black Wire

Cut the black wire approximately 2/3 inch (17mm) from the base of the battery connector.

Strip the Wire Ends

Remove a small portion of insulation from both ends of the cut wire using a wire stripper.

Use the 28 AWG notch on your wire stripper for best results.

Solder the Components

Follow the soldering diagram to connect the battery to the board. The switch goes in-line with the black (ground) wire.

Be careful with soldering! Use proper ventilation and safety equipment.

Secure the Switch

Insert the switch securely into the battery connector circuit.

Place Battery and Board in Case

Carefully place the battery and board into the 3D-printed case.

Position the Switch

Insert the switch into the notch next to the USB-C slot.

Manage the Wires

Twist the longer red wire gently to help organize it within the case.

Curl the Wire

Carefully curl the twisted wire and place it to the side to ensure it fits within the case.

Attach the Lid

Align the lid with the case using the ridges as a guide and snap it into place.

Secure the Case

Apply even pressure around the edges to ensure the seams snap securely into place.
