The mikroBUS Clicker Board is an evaluation platform that provides an easy extension to many applications. This platform consists of a series of Click Boards that are easily pluggable with the ATSAMR30M Sensor Clicker Board. The mikroBUS Click Boards support a wide range of different applications. These Click Boards are connected through a set of standardized headers and receptacles. All mikroBUS Clicker Boards contain two single row, 8-pin, 100-mil receptacles. The Clicker Boards have female connectors, while Click Boards have their male counterparts.
The mikroBUS Clicker Board receptacles (J1 and J2) provide the interface to use the ATSAMR30M Sensor Board. The following tables provide the pin details of these receptacles, respectively.
