Apart from the strong CPU, Seeed Sudio XIAO SADM21 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!

Typical Application

Wearable devices
Rapid prototyping (directly attached to the expanded PCB as a minimal system)
Perfect for all the projects need mini arduino
DIY keyboard
USB development (USB to multi-channel TTL/USB host mode, etc.)
A scenario where you need to read multiple mock values The DAC output

?Perfect for Wearable and Tiny Arduino Projects? This microcontroller 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. ?Applications? Seeeduino XIAO is suitable for Wearable devices, Rapid prototyping, DIY keyboard, USB to multi-channel TTL/USB host mode, etc. ?Fully compatible with Arduino IDE? Seeeduino XIAO development board is perfectly compatible with Arduino IDE and you can easily create small projects using the extensive and comprehensive Arduino library. It has a 2.54mm pin pitch and can be used even when inserted into a breadboard because it is an Arduino microcontroller.It has a 2.54mm pin pitch and can be used even when inserted into a breadboard because it is an Arduino microcontroller. ?Rich Interfaces in a Tiny Size? The device has 14 GPIO pins, each of which has 11 analog channels, 11 digital channels, I2C*1, UART*1, and SPI*1, USB Type-C interface*1 in a tiny space, just 20mm*17.5mm (about the size of your thumb). Seeeduino XIAO is the smallest Arduino compatible board in the Seeeduino series. ?Powerful CPU? The Seeeduino XIAO is equipped with an ARM Cortex-M0+ 32bit 48MHz microcontroller, which is three times faster than Arduino Uno and Arduino Nano. Furthermore, this Arduino IDE compatible board XIAO has 256KB flash memory and 32KB SRAM.
