ESP8266 Community Forum

I made up a digitally controlled bench power supply using an esp8266 module controlling a xl4015 buck converter via DACs. Powered by an old laptop power brick it gives 1.25V to 19V at up to 4A with fine control of the voltage and current limit.

Wow, that's looking really neat.

Personally I would classify these kinds of things as "Why would you want to make something like this? Well, because we can!", but I really like those things and this project is no exception.

Nicely done.
