PWR_SEL Jumper
The PWR_SEL jumper selects the source of power input to the module, or provides+5VDC to
J1 for use by external circuits. The module takes voltage input from the 2-position on-board
voltage regulator or from the 40-pin MCU connector (J1). Power input at the terminal block
must be DC voltage between +7VDC and +16VDC. Power input on the MCU connector must
be regulated voltage between +4.75VDC and +5.25VDC. The MCU_PORT connector power
input allows use of batteries, or other alternate sources, to power the module.
The PWR_SEL option jumper provides 3 possible configurations; source power from the PWR
connector, source power from J1, or source power from PWR and supply power to J1. The
figure below shows the settings for each configuration.
