## Porting new devices
Pull requests are welcome and encouraged to add support for new
keyboards/microcontrollers. The base requirements for device support
2019-02-25 23:10:09 +01:00
- CircuitPython
2018-10-12 04:06:10 +02:00
- 256KB of flash storage
2019-03-01 02:07:23 +01:00
- HID over USB and/or Bluetooth.

## Secondary Support
2019-02-24 04:35:00 +01:00
In the future, secondary support for lesser controllers is planned. One of
2018-10-12 04:06:10 +02:00
these cases is the pro micro being used for a slave half of a split keyboard
while all actual work is being done by a supported board. This could also be
used to convert boards that use USB or i2c that run lesser chips to a KMK
board, with a supported board acting as a translation layer. Support for
a converter is planned with the inspiration coming from the [Hasu USB to
2019-02-25 23:10:09 +01:00
USB Controller Converter](https://www.1upkeyboards.com/shop/controllers/usb-to-usb-converter/)
and would allow for conversion to KMK as opposed to TMK or QMK with that board.
