It looks like I²C because of the SDA and SCL names in the installation
instruction (

Would it be external or is there room inside the

I don't know about how it would fit inside. But I²C is one of the simpler
protocols to implement with GPIO since it's synchronized so it could use
internal GPIO or be used through UBB.
The keyboard on Ben is connected to the hardware I²C on the CPU so it cant
be used (simply at least).
