Shorted Jumper for Power Measurement
Different supplies to the headboard are provided by trace
shorted jumper, for any voltage and power measurements.
To conduct current for current measurement on a given
power rail, cut the trace between the two pins of their
respective JP, and insert an ammeter prior to powering up the
system. The figure below shows where the trace to cut is
located.
