The ESP32 development board provides a couple options for connecting a battery power source: Vin Pin: The Vin pin feeds through the onboard regulator. This allows voltages up to 16V to be stepped down to a steady 3.3V output. 3.3V Output Pin: For a regulated 3.3V supply, you can directly connect to the 3.3V output pin. Bypasses onboard regulation.
If you’re using a 9V battery or a 6x AA battery pack (providing 9V), you can connect the battery directly to the VIN pin and GND on the Arduino. The Arduino’s onboard voltage regulator will step the voltage down to 5V. Steps: Connect the positive terminal of the battery to the VIN pin. Connect the negative terminal to the GND pin.
Plug it into the Arduino’s DC barrel jack. If your battery provides a stable 5V output, such as a regulated LiPo battery with a 5V boost converter, you can connect it directly to the 5V pin on the Arduino. Warning: This method bypasses the Arduino’s onboard voltage regulator, so ensure the battery provides a steady 5V to avoid damaging your board.
In order to charge & manage the battery we will use TP4056 Battery Charger Module. We can also power this circuit using 9V/12V DC Adapter. The LM7805 Voltage regulator IC limits the voltage to 5V only. If you don’t want to power the circuit using Battery, you can use the DC Power Adapter or 9V Battery. You may check the 5V 3A USB Charger circuit.
Connect the positive terminals to the pad marked with IN+ and the negative terminals to the pad marked with IN-. Then, connect the battery holder positive terminal to the B+ pad, and the battery holder negative terminal to the B- pad. The OUT+ and OUT- are the battery outputs.
If you don’t want to power the circuit using Battery, you can use the DC Power Adapter or 9V Battery. You may check the 5V 3A USB Charger circuit. The ESP32 Board operates between 2.2V to 3.6V. But we supply 5V from Micro-USB port. For 3.3V there is already an LDO voltage regulator to keep the voltage steady at 3.3V.
