About Variations

Halberd offers acrylic laminated cases in the following two colors.

  • White
  • Black

This kit requires all the components to be soldered, but if you purchase this kit together with the "Soldering Service", you will receive the kit with all the surface mount components soldered and the firmware written, although it will take a little time.

What is Halberd?

Halberd is a 40-key, Ortholinear keyboard kit.

The main features are as follows.

  • Unique keystroke feeling with aluminum PCB top / bottom plate
  • A sense of unity with acrylic middle plate (white [half milk] or black [gray smoke])
  • Supports Backlight (SK6812MINI)

Since ProMicro is not used in the controller, it is necessary to solder parts such as MCU directly to the board, and the difficulty of assembly is a little higher, but when the kit is completed, a sense of accomplishment can be obtained.


  • This is a kit where all the parts are soldered and assembled. Difficulty level is a little high.
  • Some parts need to be purchased separately in order to complete the project. See here for details.
  • This kit is compatible with Cherry MX compatible keyswitches only.

Parts required separately

The following parts must be purchased separately to complete the kit.

  • Key switch (CherryMX compatible) x 40
  • 40 key caps
  • USB MicroB cable for PC connection
  • (Optional) Backlight 40 SK6812MINI x 40

The following sites are recommended for purchase of key switches and key caps in Japan.
