Excellent for robotics projects
Used this for a small robot controller. The dual-core processor handles WiFi and motor control simultaneously without lag. Highly recommended.

Best value ESP32-S3 board
I've tried several dev boards, and this one offers the best feature set for the price. The SD card slot is a huge plus for data logging projects.

Perfect for IoT Prototyping
This board is incredible. The screen is bright and responsive, and having the IMU and RTC built-in saves so much wiring time. Setup with Arduino IDE was seamless.

Good learning tool
As a beginner, I found the onboard components very helpful to learn about sensors and displays without needing extra modules. Just be careful with the pinout.

Great hardware, documentation could be better
The build quality is solid and the touch screen works flawlessly. I wish the wiki had more specific examples for the IMU sensor, but overall a great purchase.
Q: What is the maximum capacity for the MicroSD card?
A: The board officially supports MicroSD cards up to 32GB formatted in FAT32. Larger cards may work but are not guaranteed by the manufacturer.
Q: Is the touchscreen resistive or capacitive?
A: The 3.16-inch display features a capacitive touchscreen, which offers better sensitivity and multi-touch support compared to resistive screens.
Q: Where can I find the schematic diagrams for this board?
A: You can download the schematic diagrams, PCB files, and datasheets from the 'Resources' tab on the product page of our official website.
Q: Can I power this board with a 3.7V LiPo battery directly?
A: No, you should not connect a LiPo battery directly to the 5V or 3.3V pins. Please use a dedicated battery management module or connect via the VIN pin if your battery voltage is within the acceptable range (up to 5V).
Q: Does this board support MicroPython out of the box?
A: The board comes with a default firmware, but it is fully compatible with MicroPython. You will need to flash the MicroPython binary using a tool like esptool.py.
