SparkFun Qwiic Power Switch

The SparkFun Qwiic Power Switch (QPS) is a versatile tool for managing power in your Qwiic projects. It allows you to efficiently control power to your Qwiic devices, saving energy and extending battery life. This device is particularly useful for high-power Qwiic boards, such as high-accuracy GNSS boards, which can draw significant current even in standby mode. The QPS also features I2C bus isolation, enabling the use of both 100kHz and 400kHz I2C devices on the same bus without interference. Additionally, it includes two extra GPIO pins for added control over other project components.

Imagine a project where you need to conserve energy while still maintaining functionality. The QPS lets you selectively power down devices that aren't in use, significantly extending the life of your battery. This feature is invaluable for remote or portable applications where power conservation is crucial.

One of the standout features of the QPS is its ability to isolate slower I2C devices, preventing them from slowing down communication with faster devices. This ensures that your project runs smoothly and efficiently, even when mixing different types of I2C devices.

For projects requiring additional control, the QPS provides two extra GPIO pins that can be configured as inputs or outputs. This flexibility allows for greater control over other components in your project, expanding the possibilities of what you can create.

When used with the SparkFun Qwiic Mux, the QPS enables the control and power management of multiple devices, even those with the same I2C address. This compatibility makes it an excellent choice for complex projects with multiple components.

The QPS is supported by the SparkFun Arduino Library, which includes comprehensive examples for power switching, bus isolation, and GPIO control. This support makes it easy to integrate the QPS into your projects, allowing you to focus on innovation and creativity.
