Its small footprint and low power consumption, combined with its high performance, make this ideal for Arduino wearable devices and small projects.\u003c\/p\u003e\n\u003cp data-style=\"text-align: justify;\"\u003eIn addition to the strong CPU, Seeeduino XIAO also has 14 GPIO PINs, which can be used for 11 analog PINs, 11 digital PINs, an I2C interface, a UART interface, and an SPI interface.\u003c\/p\u003e\n\u003cp data-style=\"text-align: justify;\"\u003eSome PINs have various functions,\u003cstrong\u003e A1\/D1 to A10\/D10 Pins have PWM functions and Pin A0\/D0 functions as a DAC\u003c\/strong\u003e which means you can get true analog signals rather than PWM signals when you define it as an analog pin, that’s why 14 GPIO PINs can realize more I\/O PINs and interfaces.\u003c\/p\u003e\n\u003cp data-style=\"text-align: justify;\"\u003eMoreover, Seeeduino XIAO has a  USB-C interface which can supply power and download code. There are power pads at the back of the XIAO which support batteries and make it ideal for wearable device design. As well as the power LED, there is a user LED on board for a 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.\u003c\/p\u003e\n\u003cp data-style=\"text-align: justify;\"\u003e \u003cstrong\u003eSeeeduino XIAO is perfectly compatible with the Arduino IDE\u003c\/strong\u003e, you can easily develop small projects with the help of the large and comprehensive Arduino library.\u003c\/p\u003e\n\u003cp data-style=\"text-align: justify;\"\u003e\u003cstrong\u003eAttention: All the I\/O pins are 3.3V, please do not input more than 3.3V, otherwise, the CPU may be damaged.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"http:\/\/wiki.seeedstudio.com\/Seeeduino-XIAO\/\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eClick here for the Seeeduino XIAO WIki, which contains more specific detail as well as a handy getting started guide\u003c\/a\u003e\u003c\/p\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCPU: ARM Cortex-M0+ CPU(SAMD21G18) running at up to 48MHz\u003c\/li\u003e\n\u003cli\u003eStorage: 256KB Flash,32KB SRAM\u003c\/li\u003e\n\u003cli\u003eI\/O PINs: 14 GPIO PINs,11 analog PINs, 11 digital PINs, 1 DAC output Pin\u003c\/li\u003e\n\u003cli\u003eInterface: 1 I2C interface,1 UART interface, 1 SPI interface\u003c\/li\u003e\n\u003cli\u003ePower supply and downloading interface: USB Type-C interface\u003c\/li\u003e\n\u003cli\u003eLEDs: 1 user LED, 1 power LED, two LEDs for serial port downloading\u003c\/li\u003e\n\u003cli\u003eReset button: two reset button short connect to reset\u003c\/li\u003e\n\u003cli\u003ePower Pads: For the battery power supply\u003c\/li\u003e\n\u003cli\u003eSoftware compatibility: Compatible with Arduino IDE\u003c\/li\u003e\n\u003cli\u003eProjection cover for protecting the circuit\u003c\/li\u003e\n\u003cli\u003eDimensions: 20x17.5x3.5 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTypical Application\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eWearable devices\u003c\/li\u003e\n\u003cli\u003eRapid prototyping (directly attached to the expanded PCB as a minimal system)\u003c\/li\u003e\n\u003cli\u003eDIY keyboard\u003c\/li\u003e\n\u003cli\u003eUSB development (USB to multi-channel TTL\/USB host mode, etc.)\u003c\/li\u003e\n\u003cli\u003eA scenario where you need to read multiple mock values The DAC output\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Seeed Studio","offers":[{"title":"Default Title","offer_id":32170131816531,"sku":"SEEED-102010328","price":5.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/seeeduino-xiao-preview_1.jpg?v=1597836747","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/seeeduino-xiao","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
