![Cantor Keyboard](assets/cantor_keyboard.jpg)
The keyboard uses choc switches with choc spacing. Therefore, only MBK keycaps can be used.
There are two versions of the Cantor:
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.)

### Bill of Materials
To build the keyboard, you will need the following materials:
#### Cantor Classic:
- 2x PCB boards (both are equal since they are reversible)
- 2x STM32F401CC blackpill microcontrollers (they are cheap on aliexpress)
- Pins and sockets for the microcontrollers (blackpill needs 20 pin stripes)

- 1x TRRS cable
- 1x USB cable compatible with your computer and the blackpill
#### Cantor MX
- 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).
### Order the PCB
Download the gerber file from releases, and submit it to your favorite PCB manufacturer. The keyboard designs have been tested with JLCPCB.
