Figure 3-5. mikroBUS Socket Pinout
The AVR-BLE board features a mikroBUS socket for expanding the functionality of the development board using
MikroElektronika Click Boards 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.
