STEMMA QT / Qwiic Breadboard Breakout Adapter
PCB adapter that exposes I2C signals from a JST SH 4-pin STEMMA QT / Qwiic connector to breadboard-friendly 0.1" pins. Lets standard I2C boards without a JST SH port join a STEMMA QT / Qwiic chain.
Pinout
- SCL
I2C clock broken out from the JST SH Qwiic / STEMMA QT connectors to plated through holes; Adafruit product page states the board breaks out I2C pins and four through holes for SCL, SDA, 3.3V and GND.
Type · signalVoltage · 3.3 V I2C bus context from the same 3.3V breakout power rail; no separate level shifting claimed. - SDA
I2C data broken out from the JST SH Qwiic / STEMMA QT connectors to plated through holes; same I2C bus as the two JST SH ports.
