SparkFun Qwiic Keypad - 12 Button Category_Raspberry PI/Schede Four opto-reflector edge sensors (fifthKeypads are very handy input devices, but who wants to tie up seven GPIO pins, wire up a handful of pull up resistors, and write firmware that wastes valuable processing time scanning the keys for inputs? The SparkFun Qwiic Keypad comes fully assembled and makes the development process for adding a 12 button keypad easy. No voltage or translation figuring out which I2C pin is SDA or SCL, just plug and go! Using our handy Qwiic system, no soldering is
