Qwiic Power Switch - power switch - SparkFun PRT-26784
The Qwiic Power Switch from SparkFun allows you to more efficiently manage devices with Qwiic connectors. The switch module allows you to save power by selectively turning off selected devices. The Qwiic Power Switch has I2C bus isolation, which allows you to combine 100 kHz and 400 kHz I2C devices on the same bus. The module has been extended with additional GPIO pins that can be used to control other components in the project, and two Qwiic connectors allow for quick connection of peripherals.

Product description: Qwiic Power Switch - power switch - SparkFun PRT-26784
The Qwiic Power Switch from SparkFun allows you to more efficiently manage devices with Qwiic connectors. Many Qwiic modules, especially high-power ones, draw power even in standby mode. The switch module solves this problem by allowing you to turn off your devices, thus saving energy and extending battery life. The Qwiic Power Switch has I2C bus isolation, which allows you to connect 100 kHz and 400 kHz I2C devices on the same bus, so you can avoid slowing down communication with faster devices. The module has been expanded with additional GPIO pins , which can be used as inputs or outputs to control other components in the project. Two Qwiic connectors allow you to quickly connect peripherals without having to solder connectors and wires .
The manufacturer has provided an Arduino library and a user guide for beginners.

Qwiic Power Switch.
Features of Qwiic Power Switch
- Compatible with Arduino - the module allows you to create projects with the Arduino minicomputer
- Equipped with Qwiic connectors - has 2 Qwiic connectors that allow you to quickly connect peripherals without having to solder connectors and wires
- Built-in LEDs - indicate power on input and output pins
- Compact dimensions - the module has small dimensions, so it can be easily integrated into the project
The integrated circuit supports voltages from 2.3V to 5.5V, for compatibility with the Qwiic Connect system it is recommended to limit the input voltage to 3.3V .
Qwiic Power Switch Pinout
The button module has two Qwiic connectors on the board. There are also solder pads with the following pins:
- IN - 3.3 V - input voltage pin for the board. The recommended input voltage for this pin is 3.3 V
- OUT-3.3V - output voltage pin for the board. When the PCA9536 GPIO0 turns on the transistor, any Qwiic-enabled device connected to this side of the board will be powered by 3.3V
- GND - grounding
- IN
- SCL - I2C clock line at the PCA9306 input
- SDA - I2C data line on the input side of the PCA9306
- 3.3V - The recommended input voltage is 3.3V
- OUT
- SCL - I2C clock line at the PCA9306 output
- SDA - I2C data line on the output side of the PCA9306
- 3.3V - PCA9536 GPIO0 turns on the transistor, any Qwiic enabled device that is connected to this side of the board will be powered by 3.3V
- GND - grounding
- GPIO0 - connected to the MOSFET power switch. Controls the voltage between the 3.3V input pin and VOUT. When this transistor is off, the power is disconnected from the I2C output pull-up resistors
- GPIO1 - additional pin
- GPIO2 - additional pin
- GPIO3 - pin is connected to PCA9306, which allows for isolation of the I2C output
