This product’s been discontinued for years, so chances are yours isn’t from us. We can’t confirm its actual compatibility—we’d suggest reaching out to the manufacturer you bought it from for help. Hope you get this sorted soon!)

If the battery runs out, and the esp32 shuts down, when the usb charger is connected, does the esp32 turn again or you need to switch off and on the board?)

03:32, 17 January 2025 81.56.119.189 talk performed unknown action "comments/add" on WEMOS ESP32 Board with 18650 Battery Holder (The documents are useless are they are generic about the chips and there is no schematic for this specific board model. Anyways if anybody needs, the only way is via voltage divider to ADC pin (GPIO32 to 39) using two 100K Ohm resistors... the voltage can be calculated using the formula: (readAnalog(pin) / 4095) * 3.3 * 2 (also adding a fixed value to calibrate the result is suggested, based on measurements with multimeter))

I don't understand how the battery supply is supposed to work. The 18650 can deliver 3.7V under load. The AMS1117 has a dropout voltage of 1.1V, so in order to keep the ESP32 running at 3.3V it would need at least 4.4V on the battery which is more than it has. Even at the minimum voltage for the ESP32 of 2.55V, it would still need 3.65V from the battery which means the voltage regulator would cease to work very quickly while the battery still has lot...)
