Snap-apart NeoKeys

Use pliers to carefully snap off the top and bottom mounting strips.

Then, use your hands to carefully wiggle the extra three columns off.

Finally, remove the extra row.

Remember to save these extras somewhere safe, you can use them for another project later!

Wires

Measure and cut pieces of colored silicone covered wires for soldering the electronics.

• 1x Black & Red Wires (6 inches long)
• 1x Black & Red Wires (9 inches long)
• 3x Blue Wires (6 inches long)
• 5x White Wires (6 inches long)
• 1x Green Wire (6 inches long)
• 1x Yellow Wire (6 inches long)

Wires for Rotary Encoder

These four wires are specifically longer for the rotary encoder.

Wires for Rows

Get the four white colored wires ready to solder to the Snap-apart NeoKey switches.

Wiring Rows

Solder the four white wires to each of the Row pins on the right side of NeoKey PCB.

Wiring Columns

Solder the three blue wires to each of the Col pins on the NeoKey PCB.

VIN, GND and Data-In Wires

Solder the shorter black wire to the allocated GND pin on the NeoKey PCB.

Next, solder the shorter red wire to the designated VIN pin on the NeoKey PCB.

Then, solder the remaining white wire to the DATA-IN pin on the NeoKey PCB.

Check Wiring

Take a moment to ensure all of the wires have been properly soldered to the NeoKey PCB.

Wiring Feather

Get the Feather RP2040 ready for soldering the wired connections from the Snap-apart NeoKey PCB.

Solder Rows

Start by soldering the white wires from the NeoKey PCB (from top to bottom) to pins D12, D11, D10 and D9 on the Feather RP2040.

NeoPixel Signal

Solder the white wire from the DATA-IN pin on the NeoKey PCB to the D5 pin on the Feather RP2040.

Wiring Columns

Solder the blue wires from the Col pins on the NeoKey PCB to pins A0, A1, and A2 on the Feather RP2040.

Wiring 3V

Solder the red wire from the VIN pin on the NeoKey PCB to one of the 3V pins on the Feather RP2040.

Then, solder the longer red wire to the remaining 3V pin on the Feather RP2040.

Wiring Ground

Solder the black wire from the GND pin on the NeoKey PCB to the GND pin on the Feather RP2040.

Then, solder the longer black wire to the same GND pin on the Feather RP2040.

Rotary Wires

Solder the green wire to the D24 pin on the Feather RP2040.

Then, solder the yellow wire to the D25 pin on the Feather RP2040.

Check Wires on the Feather

Take a moment to check all of the wires have been properly soldered to the Feather RP2040.
