2x3 Header

At the top edge of the breakout is a 2x3 header that connects to the power and I2C pins on your Raspberry Pi or Pi Compatible. Line up with the edge of your chosen single board computer 2x20 GPIO connector to plug it in.

STEMMA QT Connector

• STEMMA QT - This connector, on the bottom edge of the breakout, allows you to connect to sensors and breakout boards with STEMMA QT / Qwiic connectors.
• SDA/SCL - The I2C pins for the STEMMA QT connector are connected to the default I2C port on the Pi (GPIO 2 and 3).
• 3.3V/GND - The power for the STEMMA QT connector is 3.3V. Ground is the common ground for power and logic.

Power LED and Jumper

• Power LED - To the left of the STEMMA QT port along the bottom edge of the board is the power LED. It is a green LED.
• LED jumper - This jumper is located on the back of the board and is outlined in white on the board silk. Cut the trace on this jumper to cut power to the power LED.
