Info:
All signals on the mikroBUS socket are shared with Xplained Pro extension header EXT3.
Make sure that the connected mikroBUS add-on board and Xplained Pro extension does not use the same signals if both connectors are used at the same time.
Attention: 3.3V and 5.0V are
connected directly to the mikroBUS socket. It is important to make sure the ATmega4809 operates at the same voltage as the
connected mikroBUS socket. The operating voltage for the ATmega4809 is selected with the power selection header J105.
