Seeed Studio XIAO SAMD21 carries the powerful CPU-ARM® Cortex®-M0+(SAMD21G18) running at up to 48Hz. In addition to the powerful CPU, it has 256KB Flash and 32KB SRAM on board and supports the USB Type-C interface which can supply power and download code. 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. 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. Except for the power LED, we add a user LED on board for a better coding experience. Usually, a dev board as small as this size will use the chip’s inner crystal oscillator for time fixing, in order to
