Orientation: Place the diode with the black bar facing the white closed end of the square.

  1. Solder one pad. one pad - diode
  2. While holding diode with tweezers, reflow solder and place diode down on pad. diode placed
  3. Solder other pad. diode complete
  • Note, when working with MELF package diodes, you may need to reflow and add more solder a couple times before an adequate connection is made.

Hotswap sockets

  1. Solder one pad. Hot swap socket foot print
  2. While holding hotswap socket (fingers are fine), reflow solder and place socket down on pad. Hot swap socket one pin
  3. Solder other pad. Hot swap socket
  • Note, don't hesitate to use a little extra solder, as that will help secure the socket and prevent it from being ripped off.


Orientation: Place controller with compontants facing up.

  • Note, it is recommended to flash each microcontroller prior to soldering. See firmware section for more.
  1. Solder one pad headers inserted
  2. Place microcontroller with componants facing up and reflow the soldered pad to secure the controller. microcontroller
  3. Apply solder to all pins. microcontroller



In qmk this keyboard can be found under arachnophobe. This will require a fork of QMK found here. To begin, follow the QMK setup guide. (if working from an existing installation, an update may be needed.) \ For flashing instructions, see doc or video


In Peg or KMK this keyboard can be found under arachnophobe. #TODO

Peg can be downloaded here, and the quick start can be seen here.

For Kmk can be downloaded here and the quick start can be seen here
