## Description

Buy

Review: Tiny size - Really surprising how much you can do with such a small device. Arduino programming language used to just check out simple programme.
Review: Great kit! - really nice kit, really easy to work with

## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Tiny size

### ⭐⭐⭐⭐⭐ Great kit!
*by M***K on 17 June 2021*

really nice kit, really easy to work with

### ⭐⭐⭐⭐⭐ A Great Little Board
*by T***C on 23 August 2020*

I ordered three of these Xiao boards which are about the size of a regular First Class Stamp. As a start up test, I downloaded uLisp for the Xiao to the board using the Arduino IDE appropriately set up for the SAMD21. It worked perfectly first time without any hitches although you may get confused by the fact that it switches USB Com Port allocations during the programming cycle - just use the one assigned initially if you are using an external Serial Monitor like PuTTY. The lack of I/O Pins may be off-putting but this is more than compensated by the 256K of Flash and the 48MHz clock speed. I would thoroughly recommend this board for projects needing good processing power and memory where an Arduino just won't cut it.
