Hi
I have a NodeMCU v2 (ESP8266MOD 12-F from AZ-delivery). Connected to 5V on Vin and GND.
When measuring the output voltage on a GPIO pin is: 3,5 Volt (measuring the same 3.5V at the 3,3V pin)
Q1: Is this within tolerance?
Q2: Since I want to use a GPIO to power a voltage divider for my NTC (prevent self heating), does this impact?
