Eval Board Jumper Options
There are 6 pin jumpers on the evaluation board corresponding to the 6 supplies on the board. They serve as ‘switches’ that determine if
the LDOs on board or external supplies are used for each individual supply. They are shunted by default, which means on board LDOs are
used. When an external supply is necessary, pull off the shunt from the corresponding supply and connect the external supply to the SMA
test points close to the jumper.
