Install the Adalogger FeatherWing onto the upper section on the Doubler FeatherWing.

Firmly press down to fully seat the PCB.

Install Feather

With the battery connected to the Feather RP2040 PropMaker, fit it onto the remaining section on the Doubler FeatherWing.

Firmly press down to fully seat the PCB.

Install Battery

Place the AA battery holder onto the back cover in between the four walls.

Slide the battery clip over the battery holder so the keyed edge is fitted in between the rails on the back cover.

Ensure the battery clip is fitted correctly and the battery holder is secured to the back cover.

Speaker Plate

Use four M3 x 8mm long machine screws and hex nuts to secure the speaker to the speaker plate.

Place the speaker plate over the speaker with the mounting holes lined up.

While holding the two in place, insert a machine screw and thread a hex nut to secure them together.

Repeat for all four mounting holes.

Install the Color Sensor

Use four M2.5 x 6mm long machine screws to secure the color sensor to the sensor mounting plate.

Place the color sensor over the four standoffs so the mounting holes are lined up. 

While holding parts together, insert and fasten the machine screws to secure them together.

Rotary Mounting Plate

Remove the washer and hex nut from the rotary encoder.

Insert the shaft of the rotary encoder through the hole in the rotary mounting plate.

Orient the PCB so the STEMMA QT connectors are lined up with the notches on the wall of the mounting plate.

Insert the washer over the shaft and thread the hex nut.

Firmly tighten the hex nut to secure the rotary encoder to the mounting plate.

Front Plate Installation

Orient the front plate with the case frame.

Insert the front place into the case frame. Firmly press down so the front plate sits flush with the case frame.

Secure the Front Plate

Use six M3 x 6mm long machine screws to secure the front plate to the case frame.

Insert and fasten six M3 screws to secure the front plate to the case frame.

Secure Speaker Plate

Use for M3 x 4mm long machine screws to secure the speaker mounting plate to the front plate.

Place the speaker mounting plate over the speaker standoffs on the front plate.

While holding parts together, insert and fasten the screws to secure the parts together.

Connect STEMMA QT

Get the two STEMMA QT cables ready to connect to the rotary encoder and color sensor.

Connect the longer STEMMA QT cable to the left side of the color sensor. 

Use the shorter STEMMA QT cable to connect the color sensor to the rotary encoder.

Secure the Color Sensor

Place the color sensor mounting plate over the sensor standoffs on the front plate.

While holding the mounting plate in place, insert and fasten four M2.5 x 6mm long machine screws to secure the sensor mount to the front plate.

Secure Rotary Plate

Place the rotary mounting plate over the remaining standoffs on the front plate.

While holding the plate in place, insert and fasten four M3 x 6mm long machine screws to secure the rotary mount to the front plate.

Check all the Parts

Double check all of the mounting plates are sitting flush with the front plate and all of the screws are fully tightened.

Install the Handle

Use two M5 x 8mm machine screws and hex nuts to secure the handle to the case frame.

Slide the handle over the case frame so the two mounting holes line up.

While holding parts, insert and fasten the screws to secure the handle to the case.

Insert and thread the M5 hex nuts to the screws.

Tighten the Handle

Ensure the hex nuts are fully seated. Use a pair of vise grips or pliers to fully tighten the hex nuts.

Connecting the Speaker

Insert the two colored wires from the speaker into the speaker pins on the Feather RP2040 PropMaker.

Use a slotted screw driver to secure the speaker wires to the screw block terminals.

Connect the STEMMA QT Cable

Plug in the longer STEMMA QT cable to the connector on the Feather RP2040 PropMaker.

Connected Parts

Double check the cables are secured.

Install the Storage Bin

Slide the storage bin into the case frame so the walls are fitted in between the ridges of the storage bin.

Install the Back Cover

Begin fitting the back cover over the case framing, making sure the cables are fitted inside.

Firmly press the back cover onto the case to snap fit them closed.

Install the Knob

Orient the rotary knob with the shaft of the rotary encoder.

Line up the flat edges while inserting the knob.

Firmly press the knob to fully seat the parts together.

Test the knob by rotating, ensuring it moves ok.

Power Test

Use the slide switch to power on the Feather RP2040 PropMaker.

Test the color sensor by inserting a Duplo brick and pressing the rotary encoder knob. The LED should change color to the color of the brick used.

Storing Bricks

Use the storage bin to hold a few Duplo bricks. 

Stacked bricks (5 in total) can be fitted into the storage bin.
