PDEC Connector
The evaluation kit has a 5-pin mounted connector for the position decoder module. The PDEC can be used for
quadrature, hall, and counter decoding.
Note:
External pull-ups are mounted on the three signal lines for using with passive quadrature encoders.

VCC Selection Header
The evaluation kit has a 3-pin header, labeled VCC_SEL. This header can be used to select between 3.3V and 5.0V
as the supply voltage for the PIC32CM JH01, peripherals, and extension headers by placing a jumper on the pin 1-2
or pin 2-3. Selecting 5.0V will supply the kit directly from the USB connector, or an external 5.0V source. Selecting
3.3V will supply the kit from an on-board regulator.
