Reliable and robust
Using this for a robotics project requiring camera input. The PSRAM is sufficient for buffering images. Highly recommend for intermediate to advanced users.

Great learning tool
Bought this for my university embedded systems course. Documentation is clear, and the USB-C port makes flashing code very fast. Only wish it came with a case.

Excellent performance
The vector instructions really speed up my image processing tasks. Stable connection and low power consumption in deep sleep mode.

Good value for money
Works well with the Arduino IDE right out of the box. Had a small issue with driver installation on Windows 10, but the support team helped quickly.

Perfect for AIoT Projects
This board is fantastic for my smart home sensors. The S3 chip handles Wi-Fi and Bluetooth simultaneously without issues. Setting up MicroPython was a breeze.

Best ESP32 variant yet
Upgraded from the original ESP32 and the difference in speed and peripheral support is noticeable. The Puzhong authorized version feels high quality.
Q: Does this board support external cameras?
A: Yes, the ESP32-S3 supports DVP interface for connecting external cameras, making it ideal for vision-based AI projects.
Q: Does it work with the standard Arduino ESP32 library?
A: Yes, it is fully compatible with the Arduino ESP32 core. You may need to select the 'ESP32S3 Dev Module' in the board manager settings.
Q: What is the maximum current draw for the GPIO pins?
A: Each GPIO pin can source or sink up to 40mA. However, the total current for all ports should not exceed specific limits detailed in the datasheet to prevent damage.
Q: Can I power this board with a 3.7V LiPo battery directly?
A: While the board operates at 3.3V logic, it is recommended to use a battery module with a voltage regulator or connect via the 5V pin if your battery has protection circuitry. Direct connection to GPIO is not advised.
Q: Is the Lua firmware pre-installed?
A: No, the board typically ships with a basic demo or no firmware. You will need to flash the Lua interpreter or your preferred firmware using the provided USB cable.
