SparkFun Qwiic Power Switch (QPS) is an innovative solution that enables efficient power management of devices within the Qwiic ecosystem. With QPS, you can selectively turn off Qwiic devices, such as precise GNSS modules, to save energy and extend battery life. The module also features I2C bus isolation, allowing simultaneous use of devices operating at different speeds (100kHz and 400kHz) without interference. This is the perfect solution for projects that require flexibility in managing devices.
QPS also provides two GPIO pins that can function as inputs or outputs, enabling control of other components in your project. It is also compatible with the SparkFun Qwiic Mux, allowing you to control and power multiple devices, even if they share the same I2C address. Thanks to the dedicated Arduino library, integrating QPS into projects is simple, and numerous examples make it easy to utilize functions such as power management, bus isolation, and GPIO control.
