+ Motor Temp: Right.
+ Motor Speed: I don’t know what to do with that. It all depends on the kind of sensor we’ll be using.
+ Don’t we need another on the RasPi? Nope. RasPi drives the bus and the insulation happens near the slave bridges. If we insulate near the RasPi too, we’d have to power the bus as well and we wouldn’t gain anything from it, on the contrary.
Vnevoa: Maybe you should just leave an I²C port on the board for the speed sensor… A hall sensor, whether on the motor or on the transmission.
