 This is a port of the original M0110 converter from TMK to QMK. The original converter was designed to work with **ATmega32U2** and **ATmega32U4** based microcontrollers to convert Apple M0110/M0110A keyboards and M0120 numpads to USB. This port has been tested to be compatible with the [**Adafruit Feather 32U4 BLE**](https://learn.adafruit.com/adafruit-feather-32u4-bluefruit-le).

 Simply add `BLUETOOTH = AdafruitBLE` to your `rules.mk` file. This enables code specifically for the Adafruit Feather 32U4 BLE. If enabled, the device will use the `PRODUCT` and `DESCRIPTION` values from `config.h` for the device name displayed by the Feather on host devices. You can simply change these values to change the device name.

 This port utilizes the same pins that the TMK converter used. `PD1` is used for `CLOCK` and `PD0` is used for the `DATA` from the keyboard. These pins can be changed in `config.h`.
