Key features

• •1. The complete solution takes up the least printed circuit board area. This board is used with 2.4GHz dual-mode WiFi and wireless chips using 40nm TSMC low-power technology.
• •2. The best power and RF characteristics are safe, reliable and scalable for various applications.
• •3. Meticulous workmanship: The meticulous design, perfect in workmanship, durable and long service life.
• •4. Compact and portable: being so mini and light-weight, this product does not take much space and can be easily taken away.
• •5.For Arduino IDE,choose ESP32 DEV,make sure that your program or run a program smaller than the ESP32 configuration
• •6.The maximum operating voltage of the ESP32 is 3.3V. The ESP32 has an on-board voltage regulator that can withstand voltages up to 5V using the VIN and GND pins. Once a voltage is input to the ESP32 development board's VIN pin, that voltage is passed through the ESP32's on-board voltage regulator (AMS1117), which outputs a constant 3.3V, which is the board's operating voltage. Note: The maximum operating voltage of the ESP32 is 3.3V. The maximum voltage that can be applied to the ESP32 Development Board from the VIN pin is 5V.USB power supply is 5V.
