Mysterium TKL Through-Hole Keyboard Kit

Originally designed by coseyfannitutti of and modified by me (u/piit79) to support ISO layout as well as ANSI.

WARNING! This is the first prototype which turned out to have a few faults. They will be hand-fixed by me and the kit will be fully functional:

  • The left 1u ISO key diode will be jump-wired to the correct row
  • Custom layout in QMK is required (standard Mysterium V2 ISO laout will *NOT* work correctly). The controller will be flashed with the default ISO keymap

Modified QMK firmware:
To flash your custom keymap, modify the file keyboards/42keebs/mysterium-proto/keymaps/iso/keymap.c and flash using make 42keebs/mysterium-proto:iso:usbasp

This is the last available kit that has been partially built for verification – it has all the parts (USB-C, controller, crystal, resistors, capacitors) except most of the diodes soldered.

Build your very own custom keyboard from scratch!

  • Tenkeyless (TKL) 80% layout
  • Supports both ISO and ANSI layouts
  • Easy to solder, uses only through-hole components (no SMD)
  • The only slightly tricky part to solder is the USB-C connector. If you feel a bit unsure, I can solder it for you for a small extra.
  • Optional FR4 switch plate available
  • Lead-free tinned finish, black solder mask
