I've searched the forums for any methods for esp32s3 chip input voltage (3.3v) monitoring and found nothing. I assume this would be a common issue for battery powered applications. So I have two questions : 1. Is there a API function specifically for monitoring the esp32s3 3.3v chip in...
Battery Voltage Level Monitoring Circuit When you have your ESP32 powered with batteries or solar powered as in this case, it can be very useful to monitor the battery level. One way to do that is reading the output voltage of the battery using an analog pin of the ESP32. However, the ...
It integrates a lithium battery charging management feature, ensuring safe charging of the lithium battery. This development board also supports battery voltage monitoring, enabling actions to be taken when the power level is insufficient to ensure the device's continuous operation. Support for Various...

The IP5306 is a versatile power management SOC that integrates a boost converter, lithium battery charge management, and battery level indication. The external battery can be managed with the base, and the battery charging status and remaining power can be read through I2C protocol communication. ...
If your using a battery, you naturally want to know what its capacity is. Thankfully Adafruit has our backs and exposes the battery voltage on Pin 35, a non-exposed ADC pin that we can read from. Adafruit notes on thePower Management page: ...
and can also stream FPV video from the same OV2640 camera used on the popularESP32-cammodules. The LiPo battery is held by a 3D-printed support plate screws to the bottom of the PCB. The robots can controlled by a simple web-app served by the ESP32, or a using the IMU on custom ...
