It is a pity that node.readvdd33 function () is unstable and almost unusable . Measured voltage faithfully reproduces the input voltage. This could very well be used for battery powered sensors.

really? here is my result and it seems working fine

I like ESP8266 and ESP8285 and ESP32

- Thu Feb 19, 2015 4:37 pm #10176 I read your previous post, but I prefer reliable function.
I'm tested it according to your instructions

- Thu Feb 19, 2015 10:54 pm #10188 Espressif's 0.9.6 SDK will do it well, but beta version system_get_vdd33 seems can't ue.

- Fri Mar 20, 2015 8:13 pm #12361 Testing the new version 1.0.0 it seems that neither readvdd33 nor system_get_vdd33 is working
system_get_vdd33 always returns 65535
readvdd33 is returning 764 currently but seems to return some random values on my ESP-12.
Any wiring needed to get it to Work ?

Best regards
