Ideal for Student Prototyping
We ordered ten of these for our university robotics lab. They work flawlessly with Arduino IDE and ESP-IDF. The dual-core performance is noticeable in our motor control applications.

Finally, Native USB!
No more CP210x driver issues. Plug and play recognition on Linux and Windows 11 is instant. The build quality feels premium compared to generic clones I've tried before.

Great Board, Solid Documentation
I bought this for a machine learning edge project. The NPU instructions are fast, and the board layout is clean. Pinout is clearly marked on the silkscreen which saved me time.

Good value but runs warm
Excellent functionality and connectivity. My only minor complaint is that it gets slightly warm when using Wi-Fi and Bluetooth simultaneously at high loads, but nothing a small heatsink can't fix.

Powerful but pin mapping takes learning
The chip is powerful, but remember that not all GPIOs are available on the header due to flash integration. Check the datasheet carefully before designing your shield. Otherwise, great board.

Perfect for AIoT Projects
The ESP32-S3 is a massive upgrade over the original ESP32. The native USB support makes flashing incredibly easy without needing external converters. The extra PSRAM handles my camera projects smoothly.
Q: Does it support TensorFlow Lite for Microcontrollers?
A: Yes, the ESP32-S3 is optimized for AI tasks and fully supports TensorFlow Lite for Microcontrollers, leveraging its vector instructions for faster inference.
Q: Is the PSRAM expandable or fixed on this module?
A: The PSRAM is integrated into the specific module variant you purchase (either 2MB or 8MB). It cannot be expanded externally, so please select the correct SKU for your memory requirements.
Q: Can I power this board directly with a 3.7V LiPo battery?
A: While the chip operates at 3.3V, this specific core board does not have an onboard LiPo charging circuit. You should use a regulated 5V supply via USB or a separate 3.3V regulator for battery projects.
Q: What is the maximum current draw from the 3.3V pin?
A: We recommend drawing no more than 50mA from the 3.3V pin for external sensors. For higher current requirements, please use an external regulator powered by the 5V line.
Q: Does this board come with a pre-installed bootloader?
A: Yes, the board comes with the standard ESP32-S3 bootloader pre-flashed, allowing immediate programming via Arduino IDE, MicroPython, or ESP-IDF.
