SparkFun Qwiic Power Switch

Product Overview

The SparkFun Qwiic Power Switch (QPS) gives you the power to manage your Qwiic devices more efficiently. Many Qwiic boards, especially high-power ones like our high-accuracy GNSS boards, draw significant current even in standby mode. With the QPS, you can selectively turn off these devices to conserve energy and extend your battery life.

However, the QPS offers even more functionality; it includes I²C bus isolation, allowing you to mix 100kHz and 400kHz I²C devices on the same bus without conflict. Isolate slower devices to avoid slowing down communication with faster ones.

For added flexibility, the QPS also provides two extra GPIO pins that can be used as inputs or outputs to control other components in your project. It works seamlessly with the SparkFun Qwiic Mux, enabling you to control and power multiple devices, even those sharing the same I²C address.

Our Arduino Library makes integrating the QPS into your projects easy, with comprehensive examples for power switching, bus isolation, and GPIO control. Enhance your Qwiic projects with the SparkFun Qwiic Power Switch and take control of your power management!
