Do you find yourself wishing that you had just a few more GPIO pins? What if you only need that one more pin? You could add another microcontroller to your project but that increases cost and complexity. Instead, you can use the Qwiic GPIO to add four new pins to your Qwiic project!
The Qwiic GPIO is an I²C device which adds an additional four IO pins which you can read and write just like any other digital pin on your controller. The details of the I²C interface have been taken care of for you so you can call functions similar to Arduino's pinMode and digitalWrite, allowing you to focus on your creation!
This version of Qwiic GPIO features easy-to-use latch terminals; never screw another wire into place! The terminals are relatively roomy themselves, so feel free to latch multiple wires into the ground or power terminal. Additionally, this newest version also has the red power LED you know and love.
The Qwiic GPIO comes with three customizable address jumpers allowing for up to eight Qwiic GPIO boards to be connected on a single bus allowing upwards of 32 additional GPIO pins! The default I²C is 0x27 and can be changed by cutting the traces on the back of the board.
The Qwiic GPIO uses the simple Qwiic interface, so it requires no voltage translation, no figuring out which pin is SDA or SCL, just plug it in and go!
We do not plan to regularly produce SparkX products so get them while they’re hot!
