3.10 XPRO Header (J203)

The PIC32 WFI32 2.0 Curiosity Board provides the XPRO header (J203) to have a pin-to-pin compatibility for XPRO boards. The following table provides details of the XPRO header pins:

Note:
  1. These are PPS pins that can be configured for any of the supported peripheral functions based on the end user application.
  2. For more details on the WFI32E03 pins and PTA signals, refer to the PIC32MZ W1 MCU and WFI32 Module with Wi-Fi® and Hardware-Based Security Accelerator Data Sheet (DS70005425).
  3. A jumper must be mounted on the (J210) connector to use the ID feature.
  4. A jumper must be mounted on the (J211) connector pin2 and pin3 to use this feature.
  5. Traditional Serial Communication Interface Documentation uses the terminology “Master” and “Slave”. The equivalent Microchip terminology used in this document is “Host” and “Client”, respectively.
  6. The user must not use XPRO-based touch boards and on-board temperature sensor (U204) simultaneously.
