Microswitches are an easy way to determine if your robot has hit a wall or if your gantry has reached an endstop, but why would you want to deal with debouncing, polling, and wiring up pull-up resistors? The Qwiic Switch simplifies all of those nasty worries away into an easy to use I²C device! With our Qwiic system using the switch is as simple as calling button.isPressed().

This board is BYOS, or Bring Your Own Switch. It's designed to solder onto existing microswitches, like the endstops on your CNC mill or our Arcade Joystick. We can't guarantee that it'll fit every model, but it fits our microswitches and the dimensioned Eagle files are available in the Hardware Repo. It also has a pin that connects to an external LED, which can be configured for your desired level of blinkiness!

If you need multiple switches for your project, fear not! Each switch has a configurable I²C address, so you can daisy-chain multiple switches over Qwiic and still address each one individually. We've got an example in our Arduino Library that provides a super-easy way to configure your Qwiic Switch to whatever I²C address you desire.

In addition to handling blinking and debouncing the Qwiic Switch has configurable interrupts which can be configured to activate upon a button press or click. This means that code on your microcontroller need not waste valuable processing time checking the status of the switch but instead can run a small function whenever the switch is pressed or clicked! For more information on interrupts check out our guide here!

We've also taken the liberty of implementing a FIFO queue onboard the Qwiic Switch where it keeps an internal record of when the button was pressed. This means that if you happen to be Alex Trebek and you have a network of Qwiic Switches running your Jeopardy Game, you can determine who pushed their button first without polling them constantly! This saves your microcontroller time to do other, more important things - like winning the game itself.

We've written an Arduino library to help you get started quickly. You can download the library through the Arduino library manager by searching 'SparkFun Qwiic Button' or you can get the GitHub repo as a .zip file and install the library from there.

This board is one of our many Qwiic compatible boards! Simply plug and go. No soldering, no figuring out which is SDA or SCL, and no voltage regulation or translation required!

We do not plan to regularly produce SparkX products, so get them while theyâ€™re hot!

Experimental Product: SparkX products are rapidly produced to bring you the most cutting edge technology as it becomes available. These products are tested but come with no guarantees. Live technical support is not available for SparkX products. Head on over to our forum for support or to ask a question.
