Install the active cooler to the Raspberry Pi 5. Plug in the right angle USB A extender to the Raspberry Pi.

Mount the electronics mounting plate to the back of the display with four 8mm M2.5 screws.

Mount the DRV2605L breakout to the plate with four M2.5 screws and nuts.

Remove the adhesive backing from the vibration motor and stick it to the back circular area of the mounting plate.

Attach three M2.5 standoffs and nuts to the Raspberry Pi section of the mounting plate.

Push the front plate into the main case. Attach four M2.5 screws into the four holes to mount the Raspberry Pi.

Attach the mounting plate to the Raspberry Pi with the M2.5 screws from the front plate to the three M2.5 standoffs.

Insert the ribbon cable and the display ribbon cable into the CSI/DSI extender breakout.

Insert the other end of the ribbon cable into the display.

Insert the other end of the display cable into the port on the Raspberry Pi.

You can cable manage the ribbon cables by sliding the longer ribbon cable underneath the electronics mount.

Plug the display power cable into 5V and GND on the Raspberry Pi GPIO header.

Plug the STEMMA QT cable into the haptic motor breakout. Plug the socket headers into the Raspberry Pi GPIO:

• STEMMA 3V to Pi 3.3V (red wire)
• STEMMA SDA to Pi SDA (blue wire)
• STEMMA SCL to Pi SCL (yellow wire)
• STEMMA GND to Pi GND (black wire)

Insert the power button into the button cutout on the side of the case.

Plug in the power button JST PH cable to the JST PH socket on the Raspberry Pi.

Attach the handle to the case with a knob on each side. Secure them with M4 screws and nuts.

Slide the piece of acrylic into the track in the back of the case.

Place the acrylic pull tab at the edge of the acrylic. When you're happy with the placement, secure it with some glue.

That completes the terminal assembly!

Attach the NeoKey breakouts to the mouse mount with M2.5 screws and nuts.

Run the JST end of the mouse USB cable into the mouse enclosure.

Place the mouse mount over the trackball with M3 screws. Plug the NeoKey JST cable into the BUTTON port.

Plug the JST end of the USB cable into the USB port on the trackball.

Secure the mouse assembly into the enclosure with the two M3 screws.

Place the front plate into the mouse enclosure. Plug the MX keys with keycaps onto the NeoKey breakouts.
