Ideal for university projects
Bought five of these for our senior design project. They are affordable enough to risk burning one while learning, yet powerful enough for our final demo. The USB-C connector is a huge plus.

Perfect for wearable projects
The small form factor of the XIAO ESP32-S3 is incredible. I managed to fit it into a custom smartwatch design without any issues. The Wi-Fi performance is stable and the battery life is decent for its size.

Tiny but mighty
Don't let the size fool you. This thing drives my mini quadracopter flight controller perfectly. The IMU integration works flawlessly, and the processing speed is more than enough for real-time control.

Good power management features
The deep sleep modes on the C6 model are excellent for my solar-powered sensor nodes. Only giving 4 stars because the documentation for the specific power registers could be more detailed.

Great board, steep learning curve for beginners
Hardware is fantastic and very cheap compared to competitors. However, setting up the drivers on Windows took me a while. Once working, the Arduino IDE support is seamless.

Best value RP2040 board
I bought the RP2040 version specifically for CircuitPython development. The pinout is logical, and the build quality from Seeed Studio is top-notch. Highly recommended for prototyping.
Q: What is the maximum current draw per GPIO pin?
A: For most XIAO models, the maximum current per GPIO pin is 12mA, with a total limit across all ports. Please refer to the specific datasheet for your chip variant (S3, C3, C6, etc.) for precise electrical characteristics.
Q: Is the ESP32-C6 version compatible with Matter protocol?
A: Yes, the ESP32-C6 chip supports Wi-Fi 6 and Thread, making it fully capable of running Matter protocol stacks for smart home integration.
Q: Does this board come with pre-soldered headers?
A: No, the board typically comes with a separate pin header set in the package so you can choose between soldering standard headers, female headers, or leaving them unsoldered for SMD applications.
Q: Does the SAMD21 version support Bluetooth?
A: No, the SAMD21 variant does not have built-in wireless capabilities. If you need Bluetooth or Wi-Fi, please select the ESP32-S3, C3, or C6 versions of the XIAO board.
Q: Can I power this directly from a 5V USB source?
A: Yes, you can power the board via the USB-C port which provides 5V. The on-board regulator will step this down to 3.3V for the microcontroller. You can also supply 3.3V directly to the 3V3 pin if bypassing the regulator.
