Interfacing to onsemi Demo 2X Baseboard
The onsemi Demo 2X baseboard has a similar 26−pin connector and 13−pin connector which mate with J5 and J6 of the headboard. The four mounting holes secure the baseboard and the headboard with spacers and screws.
Shorted Jumpers 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.
