Qwiic Boost

SparkFun Qwiic Boost increases the Qwiic bus from 3.3V to 5V while providing the target device with 3.3V I²C signals. The board connects technologies that still require 5V for running higher voltage mechanisms but have an internal processor running at 3.3V. 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.
