3.5.3 mikroBUS Connector

The PL360G55CF-EK board incorporates mikroBUS add-on connectors (J5 and J6) to integrate the board itself as a module which is able to interface with other microcontrollers or microprocessors (main board).

The mikroBUS standard specifies the size and shape of the add-on boards, but because of special constraints, the board exceeds those limits although keeping the smallest size model S as a reference for the plug-in area.

The PL360G55CF-EK board is designed to operate only from the +5V power supply rail of the mikroBUS socket. Therefore, +3.3V power supply pin is not connected.

Important: By default, J5 and J6 headers are not populated in the board. The 8-pin headers are included in a zip bag as kit contents.

The mikroBUS standard has a pair of 1x8 male headers with the following pinout:

  • SPI
  • UART
  • I2C
  • PWM
  • Interrupt
  • Analog input
  • Reset
  • Chip Select
  • +3.3V
  • +5V
  • Two GND pins

Notice: The mikroBUS Xplained Pro is an extension board that contains the female header to connect the mikroBUS add-on boards to the Xplained Pro MCU boards.
