Plug a Pico W and DVI PiCowbell into a PiCowbell Doubler. The Pico W should be plugged into the left side (STEMMA QT/Reset button) and the DVI PiCowbell should be plugged into the right side (JST PH battery port/slide switch).

Secure the Doubler to the bottom lid of the case with four M2.5 screws.

Plug in a JST PH cable with plug headers to the IR breakout. Make sure to select the horizontal (H) IR receiver with the slide switch.

Plug in the JST PH cables to the Doubler:

• White wire to IO2
• Red wire to 3.3V
• Black wire to GND

Gently bend the pins down so that the cables will lie flat in the case.

Attach the IR breakout to the case lid with two M2.5 screws. The back of the board should be facing up.

Snap the top and bottom lids together. That completes the assembly!
