I wanted a small power supply and this is definitely it 🙂 If you are planning a more powerful USB PD variant, I’d be very interested.
This is a great invention. A simple and affordable adjustable power supply. The browser UI is easy to use and the API is usable. The only drawback is a short voltage transient at a sudden load change.
Sehr nützliches Teil, Funktion ohne zusätzliche Treiberinstallation unter Windows und Linux getestet. Sehr gut. Webfrontend ok, RestAPI sehr nützlich. Beschreibung und Beispiele sehr nützlich. Alles in Allem empfehlenswert.
Excellent, easy to use. You should be proud of yourselves <3
Nice to have feature: not limited by the output of the USB port. Have its own PMIC and e.g. a DC input so it can support higher current/voltage. The front end should and can stay the same though, lovely clean interface. Then it would be perfect!
