# M0110(A) keyboard converter
|
|
|
|
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).

|
## Enabling Bluetooth for the Adafruit Feather 32U4 BLE
|
|
|
|
Simply add `BLUETOOTH = bluefruit_le` to your `rules.mk` file. This enables code specifically for the Adafruit Feather 32U4 BLE. If enabled, the device will use the `PRODUCT` value 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.

|
## Pins
|
|
|
|
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`.

## Other important hardware notes from the original TMK converter Readme:

|
>### Hardware
|
|
>--------
|
|
>You can buy preassembled [TMK converter] or make yourown with AVR dev board like PJRC [Teensy].
|
|
>
|
|
>Port of the MCU `PD1` is assigned to `CLOCK` line and `PD0` to `DATA` by default, you can change pin configuration with editing `config.h`.

|
>#### Pull-up Resistor
|
|
>You may need pull-up resistors on signal lines(`CLOCK`, `DATA`) in particular when you have long or coiled cable. **1k-10k Ohm** will be OK >for this purpose. In that case the converter may not read signal from keyboard correctly without pull-up resistors.
