Seeeduino XIAO Microcontroller Cortex M0+ SAMD21G18 Development Board for Arduino

Description 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 for 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 Specification
