　　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.
看看Seeeduino XIAO。多麼小的尺寸和可愛的外觀！它是Seeeduino家族中最小的成員。Seeeduino XIAO 仍然搭載功能強大的 CPU-ARM® Cortex®-M0+(SAMD21G18)，這是一款低功耗 Arduino 微控制器。另一方面，這塊小板在處理方面具有良好的性能，但需要的功率更少。事實上，它的設計體積很小，可用於 Arduino 可穿戴設備和小型項目。

　　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.
除了強大的CPU，Seeeduino XIAO在許多其他功能上都非常出色。它有14個GPIO引腳，可用於11個模擬引腳、11個數字引腳、1個I2C接口、1個UART接口和1個SPI接口。部分引腳具有多種功能， A1/D1 至 A10/D10 引腳具有 PWM 功能，引腳 A0/D0 具有 DAC 功能這意味著當您將其定義為模擬引腳時，您可以獲得真正的模擬信號而不是PWM信號，這就是為什麼14個GPIO PIN可以實現更多的I/O PIN和接口。此外，Seeeduino XIAO支持USB Type-C接口，可以供電和下載代碼。XIAO背面有電源墊，支持電池，使其專為可穿戴設備而設計，變得逼真。除電源 LED 外，我們在板上添加了一個用戶 LED，為您提供更好的編碼體驗。通常是開發人員。小到這個尺寸的板子，會使用芯片內部的晶振來定時，為了讓時鐘更準確，Seeeduino XIAO 額外佈局了32.768KHz，讓時鐘更穩定。

　　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!　
　Seeeduino XIAO 與 Arduino IDE 完美兼容，借助龐大而全面的 Arduino 庫，您可以輕鬆開發一些小項目。所以買一個，你很快就會愛上它！
