  2. Solder the diodes D1, D2, D3, D4. Make sure the line on the diodes is aligned with the lines on the pcb.
  3. Snip the excess from the diodes. Use some of the excess wire to solder through R1.
  4. Solder the headers on the Pro Micro slot. make sure that the black part of the header is on the side of the PCB that says RAW.
  5. Push the switches into the switch plate, and solder the switches, they only go one way!
  6. If you want LEDs, solder them through the switches. Remember the short leg goes in the square pad. Snip the excess.
  7. Solder the Pro Micro. Make sure the raw pin lines up with the RAW marking. Snip the excess of the headers.
  8. Screw in the spaces and the back cover.
