Power input. Adafruit says the onboard regulator takes 3-5VDC and safely converts it down for the 3V sensor
3.3V output from the onboard regulator; Adafruit says up to 100mA can be taken from this pin
Common ground for power and logic
I2C clock pin for connection to the microcontroller I2C clock line
I2C data pin for connection to the microcontroller I2C data line
Hardware reset input. Adafruit says it is pulled up by default and can be driven to ground to reset the board
End Of Conversion output. Adafruit says it toggles when a sensing conversion is ready to be read and can be left disconnected if polling over I2C
