Mysterium TKL Through-Hole Keyboard Kit

Originally designed by coseyfannitutti of and modified by 42. Keebs to support the ISO layout as well as ANSI.

This is the second prototype of the unified ANSI/ISO version. Due to a misunderstanding of the Mysterium V2 layout, it is not fully compatible with the official QMK firmware and needs a custom layout. The controller will come pre-flashed with the default ISO layout.

Modified QMK firmware – to flash your custom keymap, modify the file keyboards/42keebs/mysterium_v15_b2/keymaps/iso/keymap.c to your liking and flash using make 42keebs/42keebs/mysterium_v15_b2:iso:usbasp.

This unit is partially build – it has all the base parts (USB-C, controller, crystal, resistors, capacitors etc.) except most of the switch diodes soldered.
