Product description: Seeeduino Xiao - SAMD21 ARM Cortex M0+ - Arduino compatible
This compact module is equipped with an Arduino-compatible SAM2D1G18 ARM Cortex M0+ microcontroller with 256 KB of flash and 32 KB of SRAM. The board features 14 GPIO connectors , including 11 digital/analog pins, 10 PWM, DAC, I2C, UART, SPI, and SWD. The module's pinout is clearly labeled for easy connection. The module's pinout operates at 3.3 V. The module is powered by 5 V via a USB Type-C connector.
Some Seeeduino Xiao pins have different functions. Pins A1/D1 to A10/D10 have PWM functionality, while pin A0/D0 functions as a DAC , allowing for a true analog signal, not PWM. The Seeeduino Xiao uses a USB-C connector for power and code uploads. The board's reverse side also features pads that allow for battery power. The board can be programmed via the Arduino IDE . The module is equipped with a 32.768 kHz crystal oscillator, which ensures the system's stability.
