4.4.2 mikroBUS Socket

AVR-IoT Wx 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.

Info:

1) A 0-ohm resistor has been soldered to connect the VCC_MUX pin to the mikroBUS socket. If an add-on module cannot handle 5V on this pin, the 0-ohm resistor has to be removed. For more information, see Hardware Modifications.
