Qwiic Boost increases the Qwiic bus from 3.3V to 5V while still providing the target device with 3.3V I2C signals. This is a handy board for connecting technologies that still require 5V for running higher voltage mechanisms (like a DC fan) but have an internal processor running at 3.3V. We’ve seen this a lot with air quality sensors that use a fan to push air into a test chamber.
The 5V boost circuit is rated up to 100mA with 90% efficiency. For applications where the 5V device needs 5V I2C signals, a conversion circuit is provided with the board. A jumper is available to select between 3.3V (default) and 5V I2C signals.
