22 | 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. |

42 | 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. | |
