About this item
The SparkFun Qwiic Power Switch (PRT-26784) is a compact, easy-to-use device designed to remotely control power delivery to various components or subsystems within your electronics projects. It uses a high-side load switch IC to safely switch power on or off to connected devices, allowing you to manage power consumption efficiently and protect sensitive circuits. Integrated into the SparkFun Qwiic ecosystem, this power switch communicates via I²C using the convenient Qwiic connector system, making wiring straightforward and solderless when connecting to other Qwiic-enabled devices or microcontrollers. With its I²C interface, you can control the power state programmatically, turning peripherals on or off as needed based on system conditions, sensor readings, or user input. The board supports input voltages up to 5.5 V and can handle continuous loads up to 2 A, making it suitable for powering a wide range of sensors, actuators, and modules. Its compact design and low quiescent current make it ideal for battery-powered and energy-conscious applications. With built-in safety features like overcurrent protection and thermal shutdown, the Qwiic Power Switch ensures reliable and safe power management in your projects, enhancing modularity and control in embedded systems.
