I have the ESP32 Display, 2.8 Zoll HMI 240x320
, is there a chance to get the voltage of the Battery?
thx guys
Hello @cooljack ,
I‘m sorry you there's no method to read the battery voltage directly
Okay and Is there a non-direct way to measure the battery voltage? is there an available adac pin?
You can connect a voltage measurement circuit or module to GPIO_D port.
The pin number of GPIO_D port is IO25, you can use it as an ADC port.
