The main power supplies to the module are 3.3V, 5V, and
12V (input via connector 1701).
The back-end section mainly uses the 3.3V. On-board
linear regulators are used to generate the 2.5V or 1.8V
required by the STi55xx.
The front-end section mainly uses the 5V and 12V. An
optional on-board linear regulator can be used to generate
the 3.3V required by the front-end. The motor and servo
drivers use the 12V.
