Screws for the Mount
Get the 3D printed mount ready to attach to the snap-apart NeoKey PCB. Use the following screws to secure the mount to the PCB.
- 4x M2.5 x 6mm long steel machine screws
Install Mount
Place the 3D printed mount over the snap-part NeoKey PCB with the Feather and wires fitted through the mount.
Line up the four standoffs from the 3D printed mount with the mounting holes in the center of the NeoKey PCB.
Secure Mount
Flip the snap-part NeoKey PCB over. Insert and fasten the M2.5 x 6mm long steel screws to secure the snap-apart NeoKey PCB to the 3D printed mount.
Screws for the Rotary Encoder
Get the rotary encoder ready to attach to the 3D printed top cover.
Remove the three hex nuts from the rotary encoder.
Secure Rotary Encoder
Orient the three screws from the rotary encoder with the mounting holes on the 3D printed top cover.
Fit the rotary encoder through the 3D printed top cover with the screws going through the mounting holes.
Insert and fasten the hex nuts to secure the rotary encoder to the 3D printed top cover.
Screws for the Feather
Get the Feather RP2040 ready to secure to the 3D printed bottom cover. Use the following hardware.
- 4x M2.5 x 6mm long steel screws
Install & Secure the Feather
Place the Feather RP2040 over the built-in standoffs on the 3D printed bottom cover.
Insert and fasten the four M2.5 x 6mm long steel screws to secure the Feather RP2040 to the 3D printed bottom cover.
Secured Feather
Take a moment to ensure the Feather RP2040 has been properly secured to the 3D printed bottom cover.
Secure Mount to Bottom
Place the 3D printed mount with the snap-apart NeoKey PCB over the Feather RP2040 and 3D printed bottom cover.
Line up the remaining mounting holes on the 3D printed bottom cover with the standoffs on the 3D printed mount with the snap-part NeoKey PCB.
Insert and fasten four M2.5 x 6mm long steel screws to secure the 3D printed snap-apart NeoKey PCB to the 3D printed bottom cover.
Install Frame to Bottom
Get to install the 3D printed frame onto the 3D printed bottom cover by orienting the parts together.
Firmly press the parts together to snap fit them closed.
Check the USB-C port from the Feather RP2040 is properly lined up with the cutout on the 3D printed frame.
Connect Rotary Encoder Wires
Get the four remaining wires from the Feather RP2040 ready to connect to the screw-block terminals on the rotary encoder.
Use a screwdriver to loosen the four screws on the rotary encoder.
Insert each wire into their corresponding screw-block terminals.
- Green wire to A terminal
- Yellow wire to B terminal
- Black wire to 0V terminal
- Red wire to Vcc terminal
Use the screwdriver to secure the wires to the rotary encoders screw-block terminals.
Install Top to Frame
Orient the 3D printed top cover with the 3D printed frame.
Ensure all of the wires are fitted inside the 3D printed frame.
Press the parts together to snap fit them closed.
Key Switches
Get the twelve mechanical key switches ready to install onto the snap-part NeoKey PCB.
Take a moment to get familiar with how the key switches will need to be oriented with the socket pins on the snap-part NeoKey PCB.
Install Key Switches
Begin fitting the mechanical key switch onto the sockets on the snap-apart NeoKey PCB.
Carefully press the key switches into the sockets, being cautious not to bend the pins.
Installed Key Switches
Check the key switches are flush with the surface on the top cover.
Install the remaining key switches on to the snap-part NeoKey PCB.
Ensure all of the key switches are properly installed onto the snap-apart NeoKey PCB and top cover.
Installed Key Caps
Double check all of the key caps are fully seated onto the tems of the mechanical key switches.
