3.5 mikroBUS Socket (J200)

A mikroBUS socket (J200) expands the functionality of the PIC32 WFI32E Curiosity Board using the MikroElectronika click adapter boards.

The mikroBUS socket (J200) consists of following interfaces:
  • Two 1 x 8 female headers with Serial Peripheral Interface (SPI)
  • Inter-Integrated Circuit (I2C)
  • Universal Asynchronous Receiver-Transmitter (UART)
  • Reset (GPIO)
  • Pulse Width Modulation (PWM)
  • Analog and interrupt lines
  • 3.3V, 5V and ground power lines

The following table provides the pinout details of the mikroBUS socket (J200):

Note:
  1. For more details on the WFI32E01 pins and PTA signals, refer to the PIC32MZ W1 MCU and WFI32 Module with Wi-Fi® and Hardware-Based Security Accelerator Data Sheet (DS70005425).
  2. If using the AC243009 daughter board, the maximum frequency limit of the SPI2 interface is 12.5 MHz but the WFI32E01 Module can operate up to 20 MHz.
  3. Traditional Serial Communication Interface Documentation uses the terminology “Master” and “Slave”. The equivalent Microchip terminology used in this document is “Host” and “Client”, respectively.
  4. These are Peripheral Pin Select (PPS) pins and can be configured for any of the supported peripheral functions based on the end user application.
