Pin 35 I think So something like: float vBat; vBat = analogRead(35) * 2.0 * (3.3 / 4096.0) * 1100/1000; Serial.print("Battery voltage: "); Serial.print(vBat); Serial.println("V"); There is also a more...
This sketch for the TTGO T-Display, among other things, shows how to use the e-fuse ESP_ADC_CAL_VAL_EFUSE_VREF value to get the accurate battery reading https://github.com/Xinyuan-LilyGO/TTGO-T-Display/blob/master/TFT_eSPI/examples/FactoryTest/FactoryTest.ino Let me know if you have...
This sketch sets up a Classic BT serial port that you can monitor for a voltage readout (9600 baud) You'll need to pair your PC with the BT device called...
I would try a better USB cable
