The sensor on the breakout requires between a 2.7V and 5.5V, and can be easily used with most microcontrollers from an Arduino to a Feather or something else.
- VIN - this is the power pin. To power the board, give it the same power as the logic level of your microcontroller - e.g. for a 5V micro like Arduino, use 5V
- GND - common ground for power and logic
- SCL - I2C clock pin, connect to your microcontrollers I2C clock line. The logic level is the same as VIN and it has a 10K pullup already on it.
- SDA - I2C data pin, connect to your microcontrollers I2C data line. The logic level is the same as VIN. and it has a 10K pullup already on it.
- STEMMA QT - These connectors allow you to connectors to dev boards with STEMMA QT connectors or to other things with various associated accessories
