Adafruit Pi Stemma QT Breakout for Raspberry Pi and Compatibles

The Adafruit Pi Stemma is a small, easily removable breakout that easily adds a 4-pin JST SH pin (Stemma QT or Qwiic) connector to your Raspberry Pi. The 2x3 socket design allows you to plug securely into the Pi's I2C bus with no soldering required, Works great if you want to add a QT connector for quick I2C sensor and devices integration without any header-fiddling.

Pi Stemma has a 2x3 header on top that connects to the power and I2C pins, simply line up with the edge of the 2x20 connector on your Pi or Pi Compatible. It has a single JST SH connector that connects to your Pi's I2C bus (SDA, SCL, 3V, and Ground). It also features a 3.3V regulator, allowing it to work with all Qwiic or Stemma QT devices without risking a brownout dip. A green LED lets you know it's powered correctly. We also added two 10K pullup resistors since there are some Pi compatible boards that don't have them included.

You can use it with any Linux single board computer or microcontroller that has '2x20 Pi-compatible pinout' (there are a lot!) and then check out Blinka, our Python interface library, so you can use our huge collection of CircuitPython libraries on SBC computers using Python!
