Power Pins

• VIN - this is the power pin. Since the sensor chip uses 1.8 VDC, we have included a voltage regulator on board that will take 3-5VDC and safely convert it down. To power the board, give it the same power as the logic level of your microcontroller - e.g. for a 5V microcontroller like Arduino, use 5V
• GND - common ground for power and logic

I2C Logic Pins

• SCL - I2C clock pin, connect to your microcontroller I2C clock line. This pin is level shifted so you can use 3-5V logic, and there's a 10K pullup on this pin.
• SDA - I2C data pin, connect to your microcontroller I2C data line. This pin is level shifted so you can use 3-5V logic, and there's a 10K pullup on this pin.
• STEMMA QT - These connectors allow you to connectors to dev boards with STEMMA QT connectors or to other things with various associated accessories

Other Pins

• INT-This is the interrupt pin. You can setup the AS7341 to pull this low when certain conditions are met such as new measurement data being available. Consult the datasheet for usage
• GPIO - This is a General Purpose Input Output pin that can be controlled via the AS7341 and can be used to trigger measurements. Consult the datasheet for usage
