[IC] BLe Chiffre - nrf52 Bluetooth unified split with OLED
« on: Sat, 13 February 2021, 13:54:05 »
For your consideration today is the BLe Chiffre, the spiritual successor to my MX/Alps/Choc board Le Chiffre https://github.com/tominabox1/Le-Chiffre-Keyboard



The board features choc spacing (sorry no MX support), a holyiot nrf52 module, optional OLED support, rechargeable coin cell battery, all powered by ZMK Firmware. (no QMK will not be available) ZMK is a cool new "wireless first" firmware for nrf52 and ARM controllers. You can find out more at ZMKfirmware.dev.  ZMK provides all the great features you need for a tiny board with outstanding battery life. Even on this little coin cell, wireless life is expected to be 2-3 weeks without OLED. OLED support is still under development and battery life may improve over time.

The board is meant to be used caseless with bumpons on the bottom of the PCB.


I have not reached out for quotes yet but I would like the final price to end up below $60. Price would include the board, a battery, and bumpons.

Please fill out the form if you're interested and help pick a final color for the PCB! Thanks for stopping by! https://forms.gle/bjMk1JCMiN1EvHgY6

I love the Chiffre, but I am not sure about ZMK. From what I see, it doesn't support One-Shot Mods, and those are kind of critical for me on a layout this small.

ZMK does have sticky keys - which is the equivalent to one-shots but generic for one shot layers and one shot mods  :thumb:

This is cute! Clever name, IC is nice and concise, you have a proto, you explain all you need to about the board, this is amazing. More people should do ICs like you
