More and more power from USB-C!
Our most popular project is a tiny USB‑C negotiator that doubles as a handy little bench power supply. First introduced at Teardown 2024, this portable charger‑negotiator uses USB‑C Power Delivery and PPS to request specific voltage and current levels from a wall charger or power bank. The device is designed to fit in your pocket, hence the name Pocket Power Delivery. Since launch, we’ve expanded its firmware with a more capable interface and soon data logging support. Come check it out at our booth.
For new development, we’re now back with even more power, the full 240 W available from the latest USB‑C chargers. This capability is currently offered in a development‑board form factor, with libraries and examples ready for your Arduino platform. The board, called RotoPD Pro, can tap into Extended Power Range (EPR) and Adjustable Voltage Source (AVS), supporting a wide range of voltage increments.
