Using an external regulated 5V supply we can power ESP32 through the Vin pin by connecting the GND of ESP32 with external GND of supply. Any voltage between 5V to 12 V can be connected to an ESP32 Vin pin however it’s recommended to not use more than 6V or 7V. As ESP32 only ne...
The easiest way to power your ESP32 dev kit is to use the USB port. The dev kit includes a micro USB port through which you can both supply power to the board, and implement serial communication with the host computer for uploading a sketch. The easiest way to power your ESP32 dev ki...
The ESP32 is intended to be suitable for low power applications - in other words, running on batteries. The optimal voltage for the ESP32 is 3.3V. The nominal voltage of a Li-ion battery is 3.7V but it can be anywhere between 3V and 4.2V. Many of the development kits come with the...

We have designed hardware using ESP S3 MCU(SoC). We would like to know the program step to flash the code on our custom hardware as well as we would like to use same hardware in debug mode to test it. We have brought up VCC, GND, Tx and Rx pins on connector, please let us kn...
If the keyboard won't work, try connecting it to the 5V (VIN pin). Step 12: Power Up the Device Supply the power to the ESP32 CYD via the USB cable or VIN and GND pins. Credit for photos: Atlanta: Photo byKellyfromPexels
The ESP32-CAM AI-Thinker development board can be programmed using Arduino IDE. Learn how to program and upload code to the ESP32-CAM AI-Thinker dev board.
I'm trying to read the i2c data from a scl30 sensor co2, but the esp32 don't doing anything, I'm write the sketch with Arduino IDE, how can I read sda y scl for gpio34 and gpio35 pins? The sensor works with an arduino and, with esp32 the power supply it's on, I see the...
4) 5v power supply 5) Testing circuit Step 1: Story Few days ago, I designed a ESP32 based microcontroller development board. I revealed the Gerber files andSMT processin the previous written “Order withJLCPCB SMT assembly service”. I tested the board with different programs and Wi-fi sh...
You may like to check our previous project on high voltage measurement with other microcontrollers. Although a different microcontroller is used in these projects, you can apply the same concepts to ESP32 ADC for measurement of current, voltage, power factor and ac power. ...
