Seeeduino XIAO SAMD21 Arduino compatible microcontroller - Cortex M0+

Compact module with SAM2D1G18 ARM Cortex M0+ microcontroller, offering 256 kB Flash and 32 kB SRAM, compatible with Arduino. It features 14 GPIO connectors, including 11 digital/analogue pins, 10 PWM, DAC, I2C, UART, SPI, SWD. Features clearly labelled leads for easy connection. It operates on 3.3 V, powered by USB Type C from 5 V.

The Seeeduino Xiao is characterised by the diversity of functions of its leads: from A1/D1 to A10/D10, they support PWM, while A0/D0 provides a DAC function to generate an authentic analogue signal rather than PWM. The module uses a USB C connector for power and programming. On the back of the board there are pads for battery connection. The board can be programmed via the Arduino IDE or PlatformIO environment. It is equipped with a 32.768 kHz quartz resonator for circuit stability.
