Solid industrial control candidate
We are testing these for a new control module. The stability is impressive over 48 hours of continuous run. Only minor issue was the initial driver installation on an older Windows PC.

Powerful but needs careful pin mapping
Excellent board with great speed. Just note that the GPIO pinout differs slightly from the original ESP32, so check the schematic before connecting your sensors. Otherwise, it's fantastic.

Best value for money
Having 8MB of flash and 8MB of PSRAM at this price point is unbeatable. WiFi connection is stable, and Bluetooth LE works perfectly for my sensor gateway application.

Perfect for AIoT Projects
The dual-core performance and extra PSRAM make this board ideal for running small ML models. The native USB support simplifies debugging significantly compared to older ESP32 boards.

Great upgrade from standard ESP32
I switched to the S3 for a project requiring better USB handling and more memory. It works flawlessly with ESP-IDF. The build quality from Waveshare is solid as always.

Smooth MicroPython experience
Flashed MicroPython immediately without issues. The extra RAM allows for much larger scripts and buffers. Highly recommended for anyone moving beyond basic blinking LED projects.
Q: Does this board support Power over Ethernet (PoE)?
A: No, this specific model does not have built-in PoE support. You would need an external PoE splitter or HAT if that functionality is required for your project.
Q: Is the USB-C port capable of device mode (acting as a keyboard/mouse)?
A: Yes, the ESP32-S3 features native USB OTG support, allowing it to act as a USB device (like a HID keyboard, mouse, or MIDI controller) directly without extra chips.
Q: Can I use the Arduino IDE with this board?
A: Yes, absolutely. You can install the ESP32 board package in Arduino IDE and select the 'ESP32S3 Dev Module' to start programming immediately.
Q: Does it come with headers pre-soldered?
A: No, the board is shipped without headers soldered to allow flexibility for different mounting options. You will need to solder your own male or female headers.
Q: What is the maximum current output for the 3.3V pin?
A: The onboard LDO regulator can typically supply up to 500mA, but we recommend drawing no more than 300mA from the 3.3V pin to ensure stability under heavy WiFi load.
