Internal ADC – ESP8266

2/10/2014ADC seems to be via pin TOUT on the esp8266, but this pin on the chip doesn't seem to be connected to a pin on the outside of the board on any of the modules including the ESP-07 (as far as I can tell) I have several ESP-03's and I know TOUT is not connected to a pin on my module.

ESP8266-01 Pin Magic How to use the ESP8266-01 pins

2/10/2014The ADC is pretty linear, except at the beginning and the end (which is normal), also it has some threshold at low voltages. The ADC's reference voltage isn't really 1V, it's more like 1. 06V. But that may vary between several chips.
