TOTEM
TOTEM is a 38 keys column-staggered split keyboard. It meant to be used with a SEEED XIAO BLE or RP2040
for more info on thumb fatigue: https://getreuer.info/posts/keyboards/thumb-ergo/index.html
My issue was tendon overuse in my fingers, so low force switches & column splay worked for me
(splay is where the columns are not aligned, mapping to the fan out of the human hand, see TOTEM https://github.com/GEIGEIGEIST/TOTEM)

Project mention: Icepi Zero – The FPGA Raspberry Pi Zero Equivalent Is Now on Crowd Supply | news.ycombinator.com | 2025-07-22
After getting quite a lot of emails asking to buy one last time - I've put my Icepi onto Crowd Supply!
This is a dev board that carries an ECP5 FPGA, and has a raspberry pi zero footprint. It also has a few improvements! Notably the 2 USB-B ports are replaced with 3 USB-C ports, and it has additional indicator LED and buttons.
This board can output HDMI, read from a uSD, use a SDRAM and much more. I'm very proud the product of multiple months of work.
It is also completely open source! Check out the source on github: https://github.com/cheyao/icepi-zero
