SparkFun Digital Capacitor - Qwiic
Ever need to fine tune an oscillator circuit or RF filter? It can be tricky and repetitive switching out capacitors on a PCB. The Qwiic Digital Capacitor, complete with the NCD2400M IC, can be a great solution. Solder the nibs onto any 0603 or 0402 footprint, plug in a Qwiic cable and RedBoard, and change the capacitance in code.

With the SparkFun Qwiic Digital Capacitor Arduino Library, you can easily set and get the capacitance of the IC from 1.7 up to 200pF. You can also set the configuration mode, shunt or series, and make writes to volatile or non-volatile memory.
