However, in my application I need to have the ESP32 running continuously (powered from different power source than USB). A Teensy, ESP8266, ESP32, or Raspberry Pi can work as well but for the scope of this tutorial, we will be using a 5V Arduino populated with an ATmega328P, the SparkFun RedBoard Qwiic. 3V system esptool. When I run it off of the coin cell batteries, the ESP32 goes into a loop of automatic brownout resets and never gets powered up. The ADC conversion results provided by the ADC driver APIs are raw data. I was reading something about the board getting into the download mode because EN and Boot are active at the same time once the power turns on. The capacitor is added to the power supply close to the LED strip. The folks over at Random Nerd Tutorials offer a solution for this exact scenario using a HLK-PM03 Hi-Link 100-240V AC to 3. The ESP32 has 10 internal capacitive touch sensors. IC-Power - Anything that has to do with power delivery, or making power supplies.
