miniaturized power

dual-channel usb-c lab psu. the bench, in the browser.

ProtoV MINI plugged into a breadboard with both channels live on the lcd.

dual channel

0–20 v

a credit-card-sized supply that sits on the breadboard instead of the bench, and a web panel that talks to it over the same usb-c cable.

two independent channels, 10 mv steps, current limiting, rust on an rp2040, kicad hardware, usb-c pd up to 100 w. protov.app does web serial, ota, and multi-device lab control.

built because carrying a bench supply through montréal weather is a bad joke, and a cut usb cable is a worse one.
