This camera has 4 mounting holes, and two header strips. Only the bottom strip is connected to the sensor. The top set of breakouts is there for mechanical stability only!
- Vin - this is the power pin. Since the sensor uses 3.3V, we have included an onboard voltage regulator 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 micro like Arduino, use 5V
- 3Vo - this is the 3.3V output from the voltage regulator, you can grab up to 100mA from this if you like
- GND - common ground for power and logic
- SCL - this is the I2C clock pin, connect to your microcontrollers I2C clock line. There is a 10K pullup on this pin and it is level shifted so you can use 3 - 5VDC.
- SDA - this is the I2C data pin, connect to your microcontrollers I2C data line. There is a 10K pullup on this pin and it is level shifted so you can use 3 - 5VDC.
- INT - this is the interrupt-output pin. It is 3V logic and you can use it to detect when something moves or changes in the sensor vision path.
- STEMMA QT - These connectors allow you to connectors to dev boards with STEMMA QT connectors or to other things with various associated accessories
The 6 holes at the top of the board are provided for stability and are not connected to anything. Use these if you want your sensor to sit nice and flat on a breadboard or Perma-Proto.
