- Wed Mar 18, 2015 4:22 am #12161 It's anybody here that have a decent technical documentation about ESP8266 Internal ADC?

I am running some tests for battery voltage monitoring purposes. Does not look bad at all but lack of technical documentation makes any performance tests quite hard to quantify.

Added also a new example for a 0-5V input range with Voltage divider and LSB calculation, “the easy way”: ESP8266 internal ADC 2 – the easy way example

For a ADC Input Frontend with Auto-range capabilities in the 0-40V Input range take a look also at the new ADC Input related article
