RoverWing I2C connector

RoverWing has a port for connecting additional I2C devices. This port is connected to the I2C bus of the Feather board and thus is controlled directly by the Feather. The port uses JST SH4 connector, also known as Qwiic (SparkFun) or Stemma QT (Adafurit). The pin order matches Qwiic/Stemma QT pin order:

  • GND
  • 3.3V
  • SDA
  • SCL

This port is compatible with any 3.3V I2C device. See Cables section for list of compatible cables.

RoverWing contains I2C bus pullup resistors (1.8K), so no additional pullups are necessary.

Note

If you need to connect more than one I2C device, you can use an I2C multiplexer such as this one.
