Vendor:

Seeed Studio XIAO Series are diminutive development boards, sharing a similar hardware structure, where the size is literally thumb-sized. The code name "XIAO" here represents its half feature "Tiny", and the other half will be "Puissant".

XIAO SAMD21 with a pre-soldered header, powered by a SAMD21G18 chip is an ultra-small, high-performance universal development board, the pioneering product of the XIAO series. It supports Arduino / Micropython / CircuitPython development, which is the perfect microcontroller for you to get started with electronics.

Highlighted Features

  • High Performance: Powered by SAMD21G18 chip, operating up to 48MHz, equipped with 32KB of SRAM, and 256KB of onboard flash memory
  • Ultra-small Design: 21 x 17.5mm, Seeed Studio XIAO series classic form factor, suitable for wearable devices
  • Multiple Development Interfaces: 11x analog / 11x digital Pins, 1x I2C interface, 1x UART port, and 1 SPI port
  • Multiple Develop Platform: Support Arduino / Micropython / CircuitPython development, friendly for beginners, satisfied for electronics enthusiasts
  • Perfect for Production: Breadboard-friendly & SMD design, no components on the back

Applications

  • Wearable devices
  • Rapid prototyping (directly attached to the expanded PCB as a minimal system)
  • Perfect for all the projects that need a mini Arduino
  • DIY keyboard
  • USB development (USB to multi-channel TTL/USB host mode, etc.)
  • In a scenario where you need to read multiple mock values The DAC output
