battery voltage measurement
gillesBaubrand 2026-06-12 20:27:20 13 Views0 Replies I bought a FireBeetle 2 ESP32-C6; the battery voltage measurement system is a bit off. The two 1-MΩ resistors in the voltage divider circuit are too high. You need to reduce the value to 150 kΩ; that way, the input current on the GPIO0 pin won’t interfere with the current in the voltage divider circuit.
