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.

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.
