ESP8266+18650

Posted on Updated on

The other day I came across this nice stuff; A board with an ESP8266, a battery 18650 holder and a charging circuit. Really cool stuff.

I bought a couple of them.

I flashed it using the nice firmware ESPURNA. The firmware is a great piece of code. Thanks for that. Gràcies Xose.

An interesting thing about ESPURNA is about the way the web UI was compiled.

To install the libraries necessary to compile the code, please follow the wiki from the site. It is very explicit.

It has been running a couple of days now and everything is smooth. Need to test the sleep mode because the battery is not lasting long, about 15 hours. Charging cycles are OK too.

Nice board.
