Great performance, minor documentation gaps
The hardware is solid and the dual-core processor is very fast. I had a slight issue finding specific pinout diagrams for the XiaoZhi variant initially, but the community forums helped resolve it quickly.

Solid board for smart home projects
Using this to control various smart home devices. The range on the Wi-Fi is decent, and the power consumption is low enough for battery-operated prototypes. Would buy again.

Excellent value for money
Compared to other development boards with similar specs, this offers incredible value. The Bluetooth 5 LE works flawlessly for my sensor nodes, and the USB-C connector is a nice modern touch.
Q: Does this board support external camera modules?
A: Yes, the ESP32-S3 supports DVP camera interfaces, making it compatible with many OV series camera modules for computer vision applications.
Q: Can I power this board with a 3.7V LiPo battery directly?
A: It is recommended to use a board with a built-in charging circuit or a separate voltage regulator module when connecting a LiPo battery to ensure stable 5V input to the USB pin or VIN pin if available.
Q: What is the difference between the N8R2 and N16R8 versions?
A: The numbers indicate the memory configuration. N8R2 has 8MB of Flash and 2MB of PSRAM, while N16R8 has 16MB of Flash and 8MB of PSRAM, offering more space for larger applications and data.
Q: Does it work with the standard ESP32 libraries in Arduino?
A: Yes, most standard ESP32 libraries are compatible, but you should ensure your board manager is updated to the latest version to fully support the S3 specific features.
Q: Is MicroPython pre-installed on the device?
A: No, the board typically ships without firmware. You will need to flash the MicroPython binary yourself using a tool like esptool.py, which is a straightforward process.
