Notes:
1.
These are PPS pins and can be configured for any of the supported peripheral functions based on the end
user application.
2.
For more details on the WFI32E01 pins, refer to the
PIC32MZ1025W104 MCU and WFI32E01 Module with
Wi-Fi
®
and Hardware-based Security Accelerator Data Sheet
(
DS70005425
).
3.
The SPI2 interface on the XPRO board can operate up to 12.5 MHz, and the WFI32E01 module supports up
to 20 MHz.
4.
The JP200 jumper must be mounted on the J210 connector to use the ID feature.
5.
The JP201 jumper must be mounted on the J211 connector pin2 and pin3 to use this feature.

Temperature Sensor
Connect an analog output from the temperature sensor (Microchip TC1047A, U204) to one of the analog pins (ANN1/
CVD15/CVDR15/RPA13) of the module's ADC channel.
Note:
Short the J209 jumper to enable the temperature sensor.
