Use Grove modules to expand your application
To use 6 Grove connectors on Wio Tracker, we have to use
to open 3V3_B to power the Grove modules(D12 defaults to LOW in order to
reduce consumption).
The following code shows how to use Analog and Digital Grove modules:
Open your Arduino IDE and click on File > Examples > MC20_GPS_Traker >
