Seeeduino XIAO The Smallest Arduino Microcontroller Based on SAMD21,with Rich Interfaces, 100% Arduino IDE Compatible, desiged for Projects Need Arduino Micro, 3 pcs
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. The interfaces of Seeeduino XIAO is rich enough in such a tiny Dev. Board as well. Seeeduino Xiao VS Arduino Nano With a smaller footprint and faster speed compared to most Arduino boards here, the Seeeduino XIAO is perfect to integrate into almost any projects from wearables to small robots. Standing at only 23.5 x 17.5, this board is as small as your thumb. 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. And of course, the Seeeduino XIAO is perfectly compatible with Arduino IDE which allows you to easily develop small projects with the help of the large and comprehensive Arduino library. The Seeeduino XIAO supports the USB Type-C interface which can supply power and download code. In addition, there are power pads at the back of the XIAO which support battery and makes designing wearable devices easy and simple. Other than the power LED, we also added a user LED on board for better coding experience. Apart from the strong CPU, Seeeduino XIAO is excellent in many other functions. Despite being this small size, 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. The board is also breadboard compatible which is very rare for a small board like this!

Product Features
- [ Powerful CPU] Seeeduino XIAO carries powerful CPU ARM Cortex-M0+ 32bit 48MHz microcontroller (SAMD21G18), which is three times than Arduino Uno and Arduino Nano. In addition, this Arduino IDE compatible board Xiao is also equipped with 256KB flash memory and 32KB SRAM.
- [Rich Interfaces in a Tiny Size] There is 14 GPIO PINs, which can be used for 11 analog PINs, 11 digital PINs, 1 I2C interface, 1 UART interface, and 1 SPI interface in such a tiny size - only 20mm*17.5mm ( as small as your thumb). Seeeduino XIAO development board is the smallest Arduino compatible board in the Seeeduino series.
- [Fully compatible with Arduino IDE] The Seeeduino XIAO development board is perfectly compatible with Arduino IDE, you can easily develop some small projects with the help of the large and comprehensive Arduino library. As it has a 2.54mm pin pitch, it is an Arduino microcontroller that can be used even when inserted into a breadboard.
- [USB Type C Support] 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.
- [Perfect for Wearable and Tiny Arduino Projects] 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.
