TOTEM++ is a 50 key column-staggered choc split keyboard. It is meant to be used with a Seeed Studio XIAO nRF52840 BLE. This is an iteration on the TOTEM project by GEIST for those who like the design of the keyboard, but would like to have a few extra keys to ease the transition from larger keyboards. Here you can read about the process of making the original board.
Here you can find the KiCad files for TOTEM++.
You can use the TOTEM without a case, but here you can find one I made for it.
The build guide for the TOTEM can be found here (works for TOTEM++).
ZMK precompiled or ZMK source (recommended) for the TOTEM (wireless using the XIAO BLE)
This is TOTEM++ in a matte black PLA case.

When i was researching the ergo keyboard market, I couldnt find a keyboard better looking (and cheaper to build) than the TOTEM, but with 38 keys, it was too overwhelming to migrate to it from my TKL keyboard. To ease this transition, I added an extra row of keys (12 in total) to the design.
GEIST for creating the TOTEM keyboard.
If you build a TOTEM I would be pretty happy to see some pictures. And if you want to leave the original creator of the keyboard (GEIST) a tip you can do this here (but please don't feel pressured)
