Pinout description and connection diagram
The module communicates with the microcontroller via the I2C interface. The board is powered with the voltage from 2 V to 5 V. Its leads are solder fields, to which the goldpin connectors included in the set should be soldered and connected according to the following dependency:
- VCC - power pin from 2 V to 5 V DC
- GND - the ground of the system
- SCL - clock line of the I2C bus
- SDA - data line of the I2C bus
