Product Description:
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. Moreover, Seeed Studio XIAO SAMD21 has a Type-C interface which can supply power and download code. There are two reset button, you can short connect them to reset the board.
Except for the power LED, we add a user LED on board for your 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 make the clock more accurate, Seeed Studio XIAO SAMD21 layouts an extra 32.768KHz to make the clock more stable.
Moreover, Seeed Studio XIAO SAMD21 is friendly to the communities for its strong software compatibilities, which supports Arduino, Micropython, and CircuitPython. Except for the software, flexible I/O allows it to speak to almost any external device.
