Interfacing to ON Semiconductor Demo 3 Baseboard
The ON Semiconductor Demo 3 baseboard has a similar
52-pin connector which mates with J1 of the headboard.
The four mounting holes secure the baseboard and the
headboard with spacers and screws.
Shorted Jumper for Power Measurement
Different supplies to the evaluation board 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.
