Power Pins

This breakout requires between 2.3V and 5.5V, and can be easily used with most microcontrollers from an Arduino to a Feather or something else. Power is connected through to both sides - this board is not a power isolator.

• VCC - 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

Logic Pins

• SCL - I2C clock pin, connect to your microcontrollers I2C clock line. The logic level is the same as VCC.
• SDA - I2C data pin, connect to your microcontrollers I2C data line. The logic level is the same as VCC.
• STEMMA QT - These connectors allow you to connect to dev boards with STEMMA QT connectors or to other things with various associated accessories.

Other Pins

• EN - This is the Enable input pin. Allows you to disconnect the in and out sides when pulled low
• RDY - This is the Ready output pin. It will let you know if the peripheral is buffer-connected to the controller (and is safe to attempt communication).
