3.10 XPRO Header (J412)

The PIC32 WFI32 Curiosity HPC Board includes one XPRO standard extension male header (XPRO header (J412)) to connect to the Microchip QT7/QT8/T9 XPRO kit. 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 WFI32E02 pins, refer to the PIC32MZ W1 MCU and WFI32 Module with Wi-Fi and Hardware-Based Security Accelerator Data Sheet (DS70005425).
  3. If using the AC243009 daughter board, the maximum frequency limit of the SPI2 interface is 12.5 MHz, but the WFI32E02 Module can operate up to 20 MHz.
  4. Remove the jumper (J300) and mount resistor (R436) to use the ID feature.
  5. The user must not simultaneously use the UART-based MikroElectronika click boards on the mikroBUS socket (J400) and the QT7/QT8/T9 XPRO kit on the XPRO header (J412).
  6. Out of the box, the resistor (R339) is not mounted on the PIC32 WFI32 Curiosity HPC Board. If the user wants to use the XPRO header (J412), do not mount the resistor (R339) on the PIC32 WFI32 Curiosity HPC Board.
  7. Traditional XPRO documentation uses the terminology “Master” and “Slave”. The equivalent Microchip terminology used in this document is “Host” and “Client”, respectively.
