Description
Specifications

The Seeed Studio XIAO SAMD21, which used to be named Seeeduino XIAO, is the first debut of the Seeed Studio XIAO family, a series of powerful thumb-size dev boards compatible with Arduino. It carries the powerful ATSAMD21G18A-MU which is a low-power microcontroller. On the other hand, this little board has good performance in processing but needs less power. It is designed in a tiny size and can be used for wearable devices and small projects.

Seeed Studio XIAO SAMD21 has 14 PINs, which can be used for 11 digital interfaces, 11 mock interfaces, 10 PWM interfaces (d1-d10), 1 DAC output pin D0, 1 SWD pad interface, 1 I2C interface, 1 SPI interface, 1 UART interface, Serial communication indicator (T/R), Blink light (L) through pin multiplexing. The colors of LEDs(Power, L,RX,TX) are green, yellow, blue, and blue. Moreover, Seeed Studio XIAO SAMD21 has a Type-C interface that can supply power and download code. There are two reset buttons, you can short-connect them to reset the board.
