
Optionally set jumper JP9 to ON for
an extended buffer capacitance for all
harvesters OR
set jumper JP10 to ON for an extended
buffer capacitance for the TEG harvester
Connect your application to the power
connector
Caution:
Only one source selector MUST be set
at a time
Only one buffer cap selector MUST be set
to ON at a time
