Products like our top-end \u003ca href=\"https:\/\/www.sparkfun.com\/products\/16481\"\u003eu-blox GNSS boards\u003c\/a\u003e in particular. There are times when you wish you could switch them off to save power, and the Qwiic Power Switch (QPS) allows you to do exactly that!\u003c\/p\u003e \u003cp\u003eBased on the PCA9536 4-Bit I\u003csup\u003e2\u003c\/sup\u003eC I\/O expander, the QPS can completely disconnect any attached devices so you can minimize your current draw and extend your battery life when you need to.\u003c\/p\u003e \u003cp\u003eThe QPS also includes a PCA9306 level-translator which acts as a bus isolator.

You can leave the slower devices powered up while you do this, or completely switch them off. It�s your choice.\u003c\/p\u003e \u003cp\u003eIf that wasn�t enough, we�ve broken out the two unused GPIO pins so you can use those as extra inputs or outputs for your project too!\u003c\/p\u003e \u003cp\u003eOur \u003ca href=\"https:\/\/github.com\/sparkfun\/SparkFun_Qwiic_Power_Switch_Arduino_Library\"\u003eArduino Library\u003c\/a\u003e includes a comprehensive example showing how you can: switch the power; isolate the I\u003csup\u003e2\u003c\/sup\u003eC bus; and use those extra GPIO pins.\u003c\/p\u003e \u003cp\u003ePair some QPSs with the \u003ca href=\"https:\/\/www.sparkfun.com\/products\/14685\"\u003eSparkFun Qwiic Mux\u003c\/a\u003e and you can now not only talk to multiple devices that share the same I\u003csup\u003e2\u003c\/sup\u003eC address, you can selectively switch them off too!\u003c\/p\u003e \u003cp\u003eNeed extra Qwiic cables? \u003ca href=\"https:\/\/www.sparkfun.com\/products\/15081\"\u003eThis set covers all the options\u003c\/a\u003e.\u003c\/p\u003e \u003chr\u003e \u003cp\u003e\u003cem\u003eThe SparkFun Qwiic connect system is an ecosystem of I\u003csup\u003e2\u003c\/sup\u003eC sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector.
