Bi2C – Qwiick

Bi2C to Qwiick adapter

This board is an adapter that allows you to use Sparkfun Qwiick as well as Adafruit Stemma peripherals with the Bi2C system. You can read more about the Bi2C concept here.

The adapter is very simple and only contains the required connectors for the different systems.

When connecting Qwiick or Stemma peripherals to a Bi2C equipped micro controller board the flex cable connection must be straight, i.e. the flex cable must be turned the same way on both boards. For instance if the blue stiffener on the cable is facing down towards the board on the MCU board, it must also face down on the adapter board.

If you are attaching Bi2C peripherals to a Qwiick or Stemma board the connection needs to be flipped. This means that if the blue stiffener on the cable is facing down towards the board on the adapter board, it must face upwards on the Bi2C board.
