So we added 4 pins that can handle RX/TX communications. 
So we now have 12C and UART onboard.
Proposed uses so far:
1. Hall sensor 
2. OLED screen controller 
3. Sound controller
4. Brushless motor controller 

So far we have implemented the OLED screen but already I can see this being successful.
One big issue. What if I want to use the tacho and the OLED screen together. I can’t. That would be a real shame but the reality is it’s a 22x13mm chip. What do you expect.

The thought of adding another 12C/UART port is tempting I must say.
Work continues.

So on investigation the nRF52832 can handle two 12C streams simultaneously. Hmmmmm
