Attaching the wetware to the HAT asssembly
Step 1: Necessary parts #
- Fan (this may come attached to the top faceplate already)
- Top faceplate (note the long indent where the GPIO will pins go)
Step 2: Assembling the stirring apparatus #
This step may already be done for you. If so, move the to next step.
- Push the fan on top of the screws on the faceplate. The wire should be oriented towards the side labeled PWM. You may need to wiggle the screw ends a bit to align everything well, and apply some careful force.
Step 3: Securing the vial holder #
- Place the vial holder on top of the faceplate piece. The flat cable should follow the arrow on the faceplate.
- Holding it together, finish screwing the bottom of the faceplate. The screws will enter square nuts in the vial holder. Do not overtighten.
- The screw heads will be flush with the faceplate, and there should be no screw threads showing between the vial holder and the faceplate.
- Use the screwdriver to check that the fan can spin freely without rubbing against the screws above.
Step 4: Attaching the vial holder to the HAT #
- Place the vial holder assembly onto the Raspberry Pi/HAT.
- The GPIO pins align with the side notch of the faceplate.
- Using the 6mm screws, attach the top and bottom pieces in each corner.

Step 5: Connecting heater and stirring to the HAT #
- Open the flat flex cable connector on the HAT by pulling the tabs outward, like done previously.
- Insert the flex cable copper-side up.
- Push the tabs inward to secure the flex cable.
- Insert the stirring power connector into PWM channel 1 (unlabelled).
