Table 4-3
summarizes the power specifications.
Note:
Jumper footprints are available on board to measure power consumption on main power lines. By default, the jumpers
are not implemented. They are short-circuited by a thin PCB wire. To use this functionality, open the short circuit and
mount a 2-pin jumper.
