ADC/DAC VREF Header
The evaluation kit has a 3-pin header labeled VREF. This header can be used to select and apply a voltage reference
to the ADC and DAC. A jumper can be used to tie the ADC/DAC VREF to a filtered kit target voltage from the pin 1-2,
or an external voltage can be applied across the pin 2-3.

DAC Header
The evaluation kit has a 2-pin header labeled DAC-OUT on the board that is connected to the DAC output of the
PIC32CM JH01 and ground.

Current Measurement Header
An angled 1x2, 100 mil pin-header labeled CURRENT MEASURE is located at the upper edge of the evaluation kit.
All power to the PIC32CM JH01 is routed through this header. To measure the power consumption of the device,
remove the jumper and replace it with an ammeter.
CAUTION
Removing the jumper from the pin-header while the evaluation kit is powered may cause the PIC32CM
JH01 to be powered through its I/O pins. This may cause permanent damage to the device.

Cortex Debug Connector
The evaluation kit has a 10-pin 50-mil Cortex
®
Debug Connector that can be used to attach external debuggers to
the PIC32CM JH01.
