Robust wireless connection
Using this for a home automation hub. The dual-core processor handles multiple MQTT connections without lag. Highly recommend for serious developers.

Best value for money
I've tested many development boards, and this Waveshare version offers the best balance of price and features. The USB-C port is a nice modern touch.

Perfect for AIoT Projects
The ESP32-S3 Pico is a powerhouse. The added PSRAM makes handling image processing tasks much smoother compared to older models. Setup with Arduino IDE was seamless.

Great board, minor pinout confusion
Excellent performance and Wi-Fi range. Just be careful with the pinout diagram as some GPIOs have specific boot strapping requirements. Overall very satisfied.

Compact and powerful
The small form factor fits perfectly into my robot chassis. Bluetooth LE connectivity works flawlessly with my smartphone controller app.

Good for learning embedded systems
Bought this for my university project. Documentation is decent, and the community support for ESP32-S3 is growing fast. Wish it came with header pins pre-soldered.
Q: What is the maximum current draw from the 3.3V pin?
A: The onboard regulator can supply up to 500mA total, but we recommend keeping the load on the 3.3V pin under 300mA for stability.
Q: Can I power this board directly via the VIN pin?
A: Yes, you can supply 5V to the VIN pin. Do not exceed 5.5V to avoid damaging the onboard voltage regulator.
Q: Does it come with a USB cable included?
A: No, the package includes only the development board. A USB-A to USB-C cable is required for programming and power but is sold separately.
Q: Does this board support external antenna connections?
A: Yes, the board includes an IPEX connector for attaching an external Wi-Fi/Bluetooth antenna to improve range in metal enclosures.
Q: Is this compatible with the standard ESP32 libraries in Arduino?
A: Mostly yes. You need to install the latest ESP32 board package (version 2.0 or higher) in Arduino IDE to ensure full compatibility with the S3 architecture.
