4. Sensor connection
The Dev Kit is specifically designed to work with all different sorts of sensors, which can be attached
to its GROVE connector or to 2.54mm pin headers. This makes it a very flexible solution that can be
adjusted to specific applications and individual needs.
4.1
Grove Digital
The Grove digital modules use two signal lines called D0 and D1 . There are, for example, switch
Modules, the Fan Module, and the LED Module that controlled by digital GPIOs D0 and D1.
The following table shows the pin out of the Grove digital connector:
Pin

Grove Analog
The Grove Analog modules use two signal lines called A0 and A1 . There are, for example,
Potentiometer, Voltage Divider, and the Air Quality Module that controlled by analog pins A0 and
A1.
The following table 4.2 shows the pin out of the Grove Analog connector:
