Fast and Reliable
Upgraded from the ESP32-C3 and the speed improvement is noticeable. The extra flash memory allows for more complex firmware updates over the air.

Excellent for classroom use
We bought ten of these for our robotics workshop. Students love the dual-core capability, and the built-in antenna works well without needing external components.

Best S3 board I've tested
The power management is efficient, and the thermal performance remains cool even under continuous Wi-Fi transmission loads. Highly recommended for sensor hubs.

Great board, minor documentation gaps
Hardware is solid and performance is excellent for the price. I wish the pinout diagram in the manual was slightly clearer regarding the native USB pins, but online resources filled the gap quickly.

Good value but steep learning curve
As a beginner, I found the advanced features a bit overwhelming at first. However, once I got the basic blink example working, the potential for this board became clear.

Perfect for AIoT Projects
The 8MB PSRAM makes a huge difference when running TinyML models. Setup was straightforward using the Arduino IDE, and the Wi-Fi connection is very stable.
Q: Does this include an external antenna connector?
A: No, this specific DevKit model uses an onboard PCB antenna. If you require an external antenna connector (IPEX/U.FL), please look for the variant labeled with an external antenna option.
Q: Can I power this directly from a 3.7V LiPo battery?
A: Yes, you can connect a LiPo battery to the 5V pin if your battery has a protection circuit, or use the BAT pin if your specific variant exposes it. Please check the schematic for your specific revision to ensure safe voltage levels.
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 drawn from all GPIOs combined should not exceed the limits specified in the ESP32-S3 datasheet to avoid damaging the chip.
Q: Does this board support MicroPython out of the box?
A: The board comes with no pre-flashed firmware, but it is fully compatible with MicroPython. You can easily flash the latest MicroPython binary using esptool.py.
Q: Is the USB port suitable for high-speed data transfer?
A: The native USB port supports Full-Speed (12 Mbps) device mode. It is ideal for CDC/UART communication and HID devices, but not intended for mass storage high-speed transfers.
