3.4.9 mikroBUS Socket

The PIC32CXMTSH-DB hosts a mikroBUS socket (J21). The mikroBUS standard defines the main board sockets and add-on boards used for interfacing the microprocessor with integrated modules featuring a proprietary pin configuration. For details, refer to the mikroBUS documentation on standard specification.

8 GND GND 9 GND GND
Important: R120 and R134 are assembled, and, therefore, the pin PD16 is shared in both Xplained PRO and mikroBUS interfaces.
Warning: The mikroBUS connector is not isolated from mains.

The mikroBUS connector allows for the connection of a wide range of modules for communications, sensoring or power management applications out of the main scope for this board.
