What voltage are the GPIO pins?
Posted: Sun Apr 19, 2015 8:30 amI've tried looking around for it, incl. https://nurdspace.nl/ESP8266, but I can't quite see where the voltage of the GPIO pins is specified. Does anyone know?
Thanks

Posted: Sun Apr 19, 2015 8:37 amIt is a 3.3V nominal device, so output voltage is quite the same. Specs says 0.8 x VDD for minimal Voh with a Imax of 12mA.

I see. So is the input voltage to the GPIO also 3.3V?
Thanks
