The Arduino Xiao is the perfect microcontroller for applications where a small board profile is required in conjunction with high processing power. The ATSAMD21 is at the center of the Arduino Xiao, which is a low-power, 32-bit Arm® Cortex® -M0+ CPU running at 48 MHz. The 48MHz processor speed is 3x faster than traditional 8-bit Arduino board (ATmega328-based) which run at 16MHz. The Arduino Xiao is a great selection for projects involving wearable devices, audio processing, Internet of Things (IoT) applications, and general rapid prototyping.
