Apart from the strong CPU, Seeed Studio XIAO is excellent in many other functions. It has 14 GPIO PINs, which can be used for 11 analog PINs, 11 digital PINs, 1 I2C interface, 1 UART interface, and 1 SPI interface. Moreover, Seeed Studio XIAO supports the USB Type-C interface which can supply power and download code.

There are power pads at the back of the XIAO which support battery and make it designed for wearable devices to become realistic. Except for the power LED, a user LED has been added on board for your better coding experience.

Great form factor, but not Windows 7 supported...

While I really like the small form factor and the inexpensive price, what I didn't realize when I purchased the board was that Windows 7 is not supported. Seeedstudio do have an unsupported Windows 7 device driver available and with it my computer was able to recognize the new board in the Arduino IDE but when I tried to upload the "blink" sketch it dropped from the USB list and although I tried many things I was never able to get the board to work.
