3.5.2 mikroBUS™ Socket
The PIC-BLE board features a mikroBUS socket for expanding the functionality of the development board using the MikroElektronika Click board and other mikroBUS add-on boards. The socket is populated with two 1x8 2.54 mm pitch female headers and is ready to mount add-on boards.

Info: VBUS is
powered by USB. Consequently, +5V will not be available while the board is powered by a
battery.
Info: VCC_TARGET
will have the battery voltage when the board is powered by a battery, which can be less than
+3.3V.
