## Features
2018-05-09 09:14:30 -07:00
Some features supported by the firmware:
2019-08-30 17:52:02 -07:00
* Either half can connect to the computer via USB, or both halves can be used independently.
2018-05-09 09:14:30 -07:00
* Optional support for I2C connection between the two halves if for some
2019-08-30 17:52:02 -07:00
reason you require a faster connection between the two halves. Note that this requires 4 conductors between halves, and as such requires a TRRS cable.

## Using I2C
On the left half PCB, there's two pads labled ** *I2C Pullup*** if you want to use I2C, you need to bridge those two solder jumpers with a soldering iron.
You can change your configuration between serial and i2c by modifying your `config.h` file.
