Compact and powerful
The ESP32-S3 chip is much faster than the original ESP32. Love the USB-C port.

5 FAQ
Q: Can I program this using Arduino IDE?
A: Yes, it is fully compatible with the Arduino IDE using the ESP32 board manager package.
Q: Is there an external antenna connector?
A: No, this model uses a built-in PCB antenna. There is no u.FL connector for an external antenna.
Q: Does this board support LiPo battery charging?
A: No, this board does not have a built-in charging circuit. You will need an external TP4056 module for charging.
Q: Is the GPIO 5V tolerant?
A: No, the GPIO pins operate at 3.3V logic level. Connecting 5V directly may damage the board.
Q: What is the maximum current draw?
A: Peak current can reach around 350mA during WiFi transmission. Ensure your USB source can supply at least 500mA.
