Perfect for TinyML Projects
The AI capabilities on this board are impressive for the size. I successfully ran an image recognition model using TensorFlow Lite Micro without any lag. The camera integration was seamless.

A must-have for the XIAO ecosystem
If you already have XIAO expansion boards, this is the perfect main controller upgrade. The dual-core performance handles multitasking much better than previous single-core models.

Solid choice for edge AI
Using this for a small robot vision system. The processing power handles object detection well. Only minor issue is that the camera module sits slightly high, making low-profile cases tricky.

Best value for Wi-Fi 6 development
Upgraded from the original ESP32 and the Wi-Fi 6 support makes a huge difference in connection stability. The form factor fits perfectly into my wearable prototypes.

MicroPython runs smoothly
Flashed MicroPython immediately and had the onboard LED blinking in minutes. The battery charging circuit is a nice touch, saving me from adding external components.

Great hardware, documentation could be better
Hardware quality is top-notch as expected from Seeed. The IMU and microphone work flawlessly. However, finding specific pinout diagrams for the C6 variant took some digging in the forums.
Q: Is the Li-Po battery charger automatic when USB is connected?
A: Yes, once a Li-Po battery is connected to the JST-PH port, the board automatically manages charging when USB power is detected and switches to battery power when USB is disconnected.
Q: Does the 'Sense' version come with the camera module included?
A: No, the 'Sense' designation refers to the onboard IMU and microphone capabilities and the camera interface availability. The camera module itself must be purchased separately.
Q: Does this board support external antennas for better range?
A: Yes, the PCB includes a U.FL connector option on certain revisions, but the standard model uses the onboard ceramic antenna. Please check the specific schematic for your batch.
Q: Can I use this with the XIAO Expansion Board for OLED displays?
A: Absolutely. The XIAO series maintains a consistent pinout, so it is fully compatible with existing XIAO expansion boards including OLED, RTC, and motor driver modules.
Q: What is the maximum resolution supported by the camera interface?
A: The DVP interface supports up to UXGA (1600x1200) depending on the sensor used, though OV2640 (2MP) is the most commonly tested and optimized sensor for this board.
