ArduinoRaspberry Pi
The platforms mentioned above as supported is/are an indication of the module's software or theoritical compatibility. We only provide software library or code examples for Arduino platform in most cases. It is not possible to provide software library / demo code for all possible MCU platforms. Hence, users have to write their own software library.

Application Ideas

  • Using more I2C devices than you otherwise have room for on your Grove platform.


It does not conflict if you use the same I2C Socket simultaneously because every I2C device has its own address. Hardware installation is shown below.

Here we do not list a specific example.
