For XIAO Microcontroller-SAMD21 Cortex M0 + Nano SAMD21 48MHZ Cortex M0+ USB Type-c SPI Micro-Controller Board For Arduino

Description
Seeeduino XIAO Arduino microcontroller-SAMD21 Cortex M0+ is the smallest member of the Seeeduino series.
Seeeduino XIAO is the smallest Arduino compatible board in the Seeeduino series.
This is an Arduino microcontroller embedded with the SAMD21 chip.
The interfaces of Seeeduino XIAO is rich enough in such a tiny Dev. Board as well. 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.
