3.4.6 mikroBUS Interface

The SAM9X60-Curiosity hosts a mikroBUS socket (J8). The mikroBUS standard defines the main board sockets and add-on boards used for interfacing the microprocessor with integrated modules having a proprietary pin configuration. For details, refer to the mikroBUS documentation on web page.
