Select the ' Tools Board Seeed SAMD (32-bits ARM Cortex-M0+ and Cortex-M4) Boards Seeeduino XIAO ' menu item. This will instruct Arduino IDE what to do when you like to compile and upload a sketch. Select the ' Tools Port COMxx (Seeeduino XIAO) ' menu item. COMxx represents the COM port to which the XIAO board connects too.
Take a look at Seeeduino XIAO. What a small size and cute looking! It is the smallest member of the Seeeduino family. Seeeduino XIAO still carries the powerful CPU-ARM® Cortex®-M0+(SAMD21G18) which is a low-power Arduino microcontroller. On the other hand, this little board has good performance in processing but needs less power. As a matter of fact, it is designed in a tiny size and can be used for Arduino wearable devices and small projects.
Apart from the strong CPU, Seeeduino 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. Some PINs have various functions, A1/D1 to A10/D10 Pins have PWM functions and Pin A0/D0 has a function of DAC which means you can get true analog signals not PWM signals when you define it as an analog pin, that’s why 14 GPIO PINs can realize more I/O PINs and interfaces. Moreover, Seeeduino 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, we add a user LED on board for your better coding experience. Usually a Dev. Board as small as this size will use the chip’s inner crystal oscillator for time fixing, in order to make the clock more accurate, Seeeduino XIAO layouts an extra 32.768KHz to make the clock more stable.
Seeeduino XIAO is perfectly compatible with Arduino IDE, you can easily develop some small projects with the help of the large and comprehensive Arduino library. So get one and you will soon love it!

Driver 2 pc racing free downloadall softwares. Multiple development interfaces: 11 digital/analog pins, 10 PWM Pins, 1 DAC output, 1 SWD Bonding pad interface, 1 I2C interface, 1 UART interface, 1 SPI interface.
Note: the FTDI USB Drivers are from Arduino. But when you install drivers for other Controllers, such as Xadow Main Board, Seeeduino Clio, Seeeduino Lite,
you need to download corresponding driver file and save it. And select the driver file you have downloaded.
You should save these files which you are editing before installing driver with window8，because there will several power off during operating.
