Repo for RotoPD hardware and documentation

You can install the library directly on ArduinoIDE

While traditional power adapters can provide a variety of current but fixed to 5V output, our RotoPD leverages advanced power delivery protocols to achieve a versatile output range— 3.5V to 30V at 150W max. The breakout board use a stand alone Power Delivery Sink controller to negotiate with your modern charger and provide different output voltage.
