To take advantage of the Preonic’s new PCB, this comprehensive kit allows for expanded functionality with footprints for things like LEDs, DIP switches, power adapter plugs, Qwiic connectors, and more. First, the kit comes with 10 RGB LEDs. Pair them with an acrylic case to let the underglow really shine. Additionally, there’s a 4-channel DIP switch for toggling layouts; a 2-pin JST-PH connector for Bluetooth applications; a 4-pin Qwiic (I2C) JST-PH connector that functions with Sparkfun’s Qwiic system for external PCBs; a rotary encoder to control volume, brightness, and more; and a 6-pin male/female header for DIY projects. You can also grab the Preonic Extension Case for cutouts that allow all of these components to fit through.
