STEMMA QT
This JST SH 4-pin STEMMA QT() connector breaks out I2C (SCL, SDA, 3.3V, GND). It
allows you to connect to various breakouts and sensors with STEMMA QT connectors
() or to other things usingassorted associated accessories(). It works great with any
STEMMA QT or Qwiic sensor/device. You can also use it with Grove I2C devices
thanks to this handy cable().
There is a power pin that must be pulled high for the STEMMA QT connector to work.
This is done automatically by CircuitPython and Arduino. The pin is available in
CircuitPython and in Arduino as TFT_I2C_POWER .
Buttons
If you run into I2C or TFT power issues on Arduino, ensure you are using the
latest Espressif board support package. If you are still having issues, you may
need to manually pull the pin HIGH in your code.
