The Cantor keyboard is a 42 key diodeless split keyboard, designed with simplicity in mind. It is inspired on the popular [corne](https://github.com/foostan/crkbd), [ferris](https://github.com/pierrechevalier83/ferris) and [sweep](https://github.com/davidphilipbarr/Sweep) keyboards, aiming to provide a more ergonomic (stronger column stagger) corne-like layout with a simple, easy to assemble and cheap design.
The **Cantor Classic** uses choc switches with choc spacing. Therefore, only MBK keycaps can be used.
The **Cantor MX** uses either choc V1, choc V2, or MX switches with the slightly larger MX spacing. Keycaps for MX stems can be used. (OEM/SA/XDM/Cherry, etc.)
A diodeless design reduces the keyboard assembly time, as the amount of components to solder is significantly reduced.
Moreover, soldering diodes can cause trouble during the keyboard build. Diodes need to be placed in the correct direction, if not, the keys won't work well!
Eliminating diodes will prevent many errors during the assembly process.
- Same as the classic, but switches can be choc v1, choc v2, MX 5 pin, or MX 3pin, and the compatible keycaps for chosen switches. MX 5 pin are preferable to 3 pin because they have more points of contact with the PCB.
- Cantor MX has slots for optional 'Tenting pucks'. They can be [purchased](https://splitkb.com/products/tenting-puck) or [3d printed](https://www.printables.com/model/235433-tenting-puck-for-keyboard-tripod-mount).
Download the gerber file from releases, and submit it to your favorite PCB manufacturer. The keyboard designs have been tested with JLCPCB. More details on the ordering process can be found in the [PCB Ordering Guide](doc/pcb_ordering_guide.md).
The Cantor keyboard uses the QMK firmware. Firmware for this keyboard is coming soon to the main QMK repository with [this PR](https://github.com/qmk/qmk_firmware/pull/16552).
To flash the firmware to the microcontroller connect the blackpill to your computer and set it to bootloader mode. To do this the first time:
1. Press and hold the BOOT0 button.
2. Press and release the NRST button.
3. Release the BOOT0 button.
The following times you want to flash the keyboard, it is much simpler thanks to bootmagic. Hold the top left key of the keyboard and plug the microcontroller. If flashing the right part, hold the top right key.
