Wiring
Slide Switch Wires
Prepare a set of three wires about 4.5 inches (11.4cm) in length.
Using wire strippers, remove a bit of insulation from the tips of each wire.
Tin the exposed wire by applying a bit of solder to them.
Snip off one of the leads on the slide switch, either the far left or right but not the middle. Then trim the two remaining leads short, about half their length.
Solder two of the wires to each of the leads on the slide switch.
A pair of helping hands can assist while soldering wires in place.

Solder the two remaining wires from the slide switch to the GND pin on the Feather.
I2S Amplifier Wires
Prepare a set of five colored wires (green, blue, yellow, red and black) about 3in (7.6cm) in length.
Using wire strippers, remove a bit of insulation from the tips of each wire.
Tin the exposed wire by applying a bit of solder to them.
Make the following solder connections.
- Yellow wire to LRC
- Blue wire to BCLK
- Green wire to DIN
- Black wire to GND
- Red wire to VIN
Connect I2S Amplifier to Feather
Solder the wires from the I2S amplifier to the Feather.
- Yellow Wire to Pin #11

NeoPixel Stick Wires
Prepare a set of three colored wires (black, red and green) about 5in (12.7cm) in length.
Make the following solder connections.
- Green wire to DIN
- Red wire to 5VDC
- Black wire to GND
Connect NeoPixel to Feather
Solder the wires from the NeoPixel stick to the Feather.
- Red wire to BAT pin
- Green wire to Pin #4
Toggle Switch Wires
Prepare a set of two colored wires (white and black) about 5in (12.7cm) in length.
Solder the black wire to the middle pin.
Solder the white wire to either the far left or right pin.
Connect Toggle Switch to Feather
Solder the wires from the toggle switch to the Feather.
- White wire to pin #25
I2S Mic Wires
Prepare a set of five colored wires (black, green, blue, yellow, and red) to about 5in (12.7cm) in length.
Solder the wires to the pins on the I2S mic.
- Yellow wire to LRCL
- Green wire to DOUT
- Blue wire to BCLK
- Black wire to GND
- Red wire to 3V
Connect I2S Mic to Feather
Solder the wires from the I2S mic to the Feather.
- Blue wire to Pin #5
- Yellow wire to Pin #6
- Green wire to Pin #9
Potentiometer Wires
Prepare a set of seven colored wires (two red, two white, three black) about 6in (15cm) in length.
Solder a red wire to the left pin on one of the potentiometers.
Solder a white wire to the middle pin on the potentiometer.
Solder a black wire to the right pin on the potentiomter.
Connect Potentiometers
On the second potentiometer, solder a black wire and the black wire from the first potentiometer to the matching pin on the right.
Solder the remaining white wire to the middle pin on the second potentiometer.
Solder the remaining red wire to the left pin on the second potentiometer.
Assemble Button to Plate
Get the two choc key switches and the 3D printed button plate ready.
Firmly press the chock key switches into the cutouts in the button plate.
Make sure the key switches are install in the correct orientation.
Button Wires
Prepare a set of four colored wires (two blue, two black) about 5in (12.7cm) in length and one of the black wires shorter about 2.5 inches (6.3cm).
Wire Potentiometers and Buttons
Solder the free hanging black wire from the potentiometer to the middle pin of one of the key switches along with the new shorter black wire.
Solder the shorter black wire and the longer black wire to the middle pin on the second key switch.
Solder one of the blue wires to the remaining pin on the key switch.
Solder the remaining blue wire to the last open pin on the other key switch.
Slide Potentiometer Wires
Prepare a set of three colored wires (red, yellow and black) about 5 inches (12.7cm) in length.
Solder the red wire to pin #1 on the slide potentiometer.
Solder the yellow wire to pin #2 on the slide potentiometer.
Solder the black wire to pin #3 on the slide potentiometer.
Connect Slide Pot to Feather
Solder the yellow wire from the slide potentiometer to pin A0 on the Feather.
Connect Rotary Pots to Feather
Solder the white wire from the first potentiometer to pin A1 on the Feather.
Solder the white wire from the second potentiometer to pin A2 on the Feather.
Connect Buttons to Feather
Solder the blue wire from the first key swich to pin A3 on the Feather.
Solder the blue with from the second key switch to pin #24 on the Feather.
3V Wire
Prepare a single red wire, about 5 inches (12.7 cm) in length.
This wire will connect from Feather 3V pin to the Wago block connector.
Speaker Wires
Cut off the connector from the mini oval speaker.
Use a pair of wire strippers to remove a bit of insulation from both wires.
Apply a bit of solder to tin the exposed wire.
