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.
an excellent device, works well for testing LEDs. very nice to use and control.
Works perfectly fine to power small sensor nodes and test them against different power profiles. I was able to completely replace three bench top instruments and make my setup portable. I suggested it to all my colleagues and students in my laboratory. My only suggestion is to provide a way to save/download I/V log files.
