Build Steps
- Prepare Diodes
- Install Diodes
- Solder Pro Micro Headers
- Install Pro Micro Controller
- Solder OLED (Optional)
- Solder Switches
- Solder Encoders (Optional)
- Case Setup
1. Prepare Diodes
If you’re using through hole diodes, bend them into shape. Here, I’m just bending it around my finger
Another way to do it, resistors shown here
Strip of diodes bent
Ripping off the paper holding all the resistors together. Grip the diodes tightly so they don’t bend as you’re ripping the paper off.

2. Install Diodes
Install diodes to the top of the PCB. Solder diode pins where they stick out of the bottom of the PCB. 48 diodes must be used for all switches to function.
Diodes are direction sensitive. Be sure to install all diodes with the black side aligned to the side with the square solder pad and line through the diode outline (as shown in illustration).
