The XIAO Development Board From Seeeduino Packs a Powerful Processor in a Tiny Footprint
Seeed Studio’ Latest entry in their Arduino based Seeeduino family Comes to a tiny 23.5mm x 17.5mm dimension. The XIAO Development Board packed with Microchip’s ATSAMD21 microcontroller. The XIAO Development Board can be easily integrated into any wearables project . The Seeeduino XIAO is also a breadboard-friendly development board that’s similar to Adafruit’s Trinket M0 and Attiny85 based digispark. The only difference is it packs a more advanced processor (ATSAMD21G18 vs. ATSAMD21E18), adds more GPIOs, and is significantly smaller in size.
The XIAO Development Board features a 32-bit Arm Cortex-M0+ CPU with a 256Kb of Flash memory and 32Kb of SRAM. The XIAO is offering 14 GPIO pins, 11 analog pins, 11 digital pins, 10 PWM pins, and a DAC pin. It also packed with I2C, UART, and SPI interfaces. Along with a USB Type-C port, Few LEDs, one reset button, power out pads (for battery power). It has an operating voltage of 3.3V.

The back of the Seeeduino XIAO features four power pads designed for hooking batteries for battery-powered operations. This makes the development board ideal for wearables and other portable projects that don’t require connected power. SeeedStudio also states that they have added an extra 32.768KHz to the MCU’s internal crystal oscillator. For Help on time fixing with added stability and accuracy. Wich is a better way of approach from SeedStudio
Programming the board made simple as well the board makes use of the Arduino IDE and its extensive library. SeeedStudio is currently offering the Seeeduino XIAO on its product page. Which retails for just $4.90,.Making it one of the cheapest SAMD21-based boards on market right now!
