Solid choice for production prototypes
Used this for a rapid prototype of a visual inspection tool. The stability of the ESP32-S3 core combined with the sensor suite saved us weeks of development time. Highly recommended.

Excellent for student projects
We bought a batch for our university robotics club. Students love the Python support. Only wish it came with a protective case in the box, as the components are quite exposed during prototyping.

Perfect for TinyML Projects
The onboard camera and microphone make this board incredible for edge AI projects. Setting up TensorFlow Lite was straightforward, and the performance is surprisingly fast for such a small footprint.

Best value in the XIAO series
I've used the SAMD21 and RP2040 versions, but this Sense version takes it to the next level. The battery charging circuit works flawlessly, and the Wi-Fi range is excellent for my smart home sensors.

Great hardware, minor documentation gaps
Hardware quality is top-notch as expected from Seeed. The pinout is compact but logical. I deducted one star because the specific pin mapping for the camera on the C6 version took some digging to find in the docs.

Compact powerhouse
Don't let the size fool you. This board handles image processing tasks that usually require much larger boards. The USB-C connector is sturdy, and the breadboard compatibility is a huge plus.
Q: What is the maximum resolution supported for AI inference?
A: While the camera can capture higher resolutions, for optimal AI inference speed on TinyML models, we recommend using resolutions like QVGA (320x240) or VGA (640x480).
Q: Can I power this directly with a 3.7V LiPo battery?
A: Absolutely. The board features a built-in lithium battery charging chip and a JST PH 2.0mm connector specifically designed for single-cell LiPo batteries.
Q: Is the camera module included or sold separately?
A: The camera module is integrated directly onto the 'Sense' version of the board. If you purchase the non-Sense variant, the camera is not included.
Q: Is this compatible with the XIAO expansion boards?
A: Yes, this board adheres to the standard XIAO form factor and is fully compatible with all official Seeed Studio XIAO expansion boards and third-party accessories designed for the series.
Q: Does this board support external antennas for better Wi-Fi range?
A: Yes, most models in the XIAO ESP32 S3/C3/C6 Sense series include an IPEX connector for attaching an external antenna, though you may need to solder a zero-ohm resistor to switch from the onboard ceramic antenna.
