Welcome to the jorian wiki!

Version 1.0 (Revision A, Jorian Christmas Edition)

  • 100x100mm PCB, made in KiCad, manufactured by Elecrow, $11.46 total for 10 PCBs, including shipping (Christmas sale)
  • YJ-14015 Bluetooth module (costs about $2) or nRF51822-CoreB, 4-pin SWD header for ST-LINK/V2
  • RGB backlighting support (44 LEDs, SK6812mini or 3.5 mm WS2812B, I used a cheap 3535 LED strip)
  • Reversible I2C display (SSD1306) support (mind that there's no much place for it if you're using a battery holder)
  • Reversible 03962A Li-Po charger board support (also supports a separate SOT-23-5 3.3V voltage regulator)
  • CR2032 BS-7 battery holder support (both for CR2032 or LIR2032 if you're using a Li-Po charger)
  • Cherry MX, Low Profile Kailh and ALPS switches support (also can be used as a switch plate)

Jorian RGB

  • Press 3 thumb keys to toggle RGB modes (hardware shortcut, you can't change it in QMK)
  • LEDs require charging (03962A chargers, red LED is power on, blue LED is fully charged)
  • Receiver is built from BlueMicro51 board and 3.3V Pro Micro (no level shifters)
  • First LED in the strip blinks blue on power on

Firmware

You need both Radio (for the halves and the receiver) and QMK firmware (for the Pro Micro). Note that you can also use an unmodified Mitosis firmware (pins are the same). There's also an incomplete Bluetooth firmware (no RGB support, no QMK layout support).

Jorian RGB firmware

Radio firmware

See uploading instructions here: https://github.com/joric/bluetosis/wiki/Uploading (do not flash softdevice, because it's not Bluetooth, it uses Nordic proprietary Gazell protocol)

QMK firmware

This is the software layout (for the Pro Micro). See the Layout article for the reference.

To flash QMK, briefly short RST and GND on Pro Micro and run this (COM11 for example):

avrdude -p atmega32u4 -P COM11 -c avr109 -e -U flash:w:mitosis_jorian.hex
  • Source code (250k baud as well, build with make mitosis:jorian)

Instructional Video

build.cmd from the video:

set file=custom\armgcc\_build\nrf51822_xxac.hex
cd custom\armgcc && bash -c "make" || exit

cd %~dp0

-c init -c "reset halt" -c "flash write_image erase %file:\=/%" -c "reset" -c exit
