Great for learning ESP32-S3
Bought this for my university embedded systems course. It works flawlessly with the Arduino IDE and the documentation provided by Waveshare is helpful.

Perfect for compact IoT projects
This board is incredibly small yet powerful. The native USB support makes flashing sketches a breeze without needing external converters. Great for wearable tech.

Bluetooth LE works perfectly
I needed a board specifically for BLE sensors and this delivers. Connection is stable and the power consumption seems optimized for battery operations.

Good value but pins are tight
The performance is excellent for the price point. My only complaint is that the pin headers are very close together, making it tricky to solder jumper wires without a breakout board.

Tiny footprint, huge potential
Amazing how much functionality they packed into such a small form factor. Ideally suited for drones or small robots where weight and space matter.

Solid board, minor heating
Runs complex WiFi tasks well. I noticed it gets slightly warm during sustained high-load transmission, but nothing concerning for normal usage scenarios.
Q: What is the maximum current this board can supply to peripherals on the 3.3V pin?
A: We recommend drawing no more than 500mA total from the 3.3V regulator to ensure stability. For high-current devices, please use an external power source.
Q: Does this board support Power Delivery (PD) charging via the USB-C port?
A: The USB-C port supports data transfer and 5V power input for programming and operation, but it does not support advanced USB-PD negotiation for higher voltages.
Q: Is there a reset button on the board?
A: Yes, there is a dedicated RST button to manually reset the microcontroller, along with a BOOT button for entering download mode.
Q: Can I use this with MicroPython out of the box?
A: Yes, the ESP32-S3 chip is fully compatible with MicroPython. You will need to flash the appropriate firmware binary first, which is easily done using esptool.
Q: Are the GPIO pins 5V tolerant?
A: No, the ESP32-S3 operates at 3.3V logic levels. Applying 5V directly to the GPIO pins may damage the microcontroller. Please use a logic level shifter if interfacing with 5V devices.
