Test Circuit

With the components wired up, it's time to connect them together and test out the circuit. Plug in the female JST connector from the switch to the Circuit Playground Bluefruit. Plug in the battery to the male JST connector to the switch. Flip the toggle switch to power on the Circuit Playground Bluefruit.

Pumpkin Screws

Locate the four screws on the bottom of the pumpkin. These screws hold the bottom cover to the pumpkin.

Remove Bottom

Using a Phillips screw driver, unfasten the four screws from the bottom cover. Keep the screws as you'll need them to secure the 3D printed mount to the pumpkin.

Test Fit 3D Printed Bottom

Now is a good time to test fit the 3D printed bottom cover. Orient the bottom cover so the notch and mounting holes are lined up. Press fit the mount into the recessed area on the bottom of the pumpkin. Remove the bottom once it has been test fitted.

Install STEMMA Speaker

The STEMMA speaker PCB snap fits into the center of the 3d printed mount. Insert the PCB at an angle and fit one side underneath one of the tabs. Press the PCB to snap fit it into place.

Installing Battery

The 500mAh battery will be placed in between the STEMMA speaker PCB and Circuit Playground Bluefruit PCB.

Battery Placement

Place the battery on top of the STEMMA speaker PCB. Adjust the cable so its position on top of the battery. Orientation of the battery can be adjusted later for better cable management.  

Installing Circuit Playground Bluefruit

Place the CPB on top of the battery. Orient the CPB so the 3.3V and GND pads are lined up with the tabs. The mount is symmetrical so it can be position in either orientation. Insert the PCB at an angle and fit it underneath the tab with the protruding post. Place the CPB so one of the post fits into one of the pads.

Installed Circuit Playground Bluefruit

Adjust the wiring so it is not being pinched or kinked. Press the CPB down to snap fit it into the second tab.

The PCB mount is designed to be symmetrical so the Circuit Playground Bluefruit can fit in either orientation.

Wire Adjustments

Thoroughly inspect the components and wiring. There's just enough clearance for the components and wiring to be sandwiched in between the two PCBs.
