Seeed Studio XIAO SAMD21 Development Board
Seeed Studio XIAO SAMD21 development board with Cortex-M0+ processor, 48 MHz, USB Type-C and Arduino compatibility for IoT and wearable projects.
The Seeed Studio XIAO SAMD21 Development Board is a fully Arduino-compatible development board built around a 48 MHz ARM Cortex-M0+ SAMD21 microcontroller from Microchip. Its compact design and built-in USB Type-C connector make it suitable for a wide range of projects, from TinyML and smart wearable devices to intricate IoT projects.
Performance and Memory
- Processor: ARM Cortex-M0+ core (SAMD21G18)
- Maximum speed: up to 48 MHz
- SRAM: 32 KB
- On-board Flash memory: 256 KB
The board provides ample resources for complex code and data while maintaining a small footprint of 21 x 17.5 mm, roughly the size of a thumb. This makes it well suited to space-constrained wearable devices and compact projects.
Connectivity and Prototyping
- Analogue pins: 11
- Digital pins: 11
- Communication interfaces: 1 I2C, 1 UART and 1 SPI
- USB Type-C connector
The breadboard-friendly SMD design, with no components on the back, supports simple prototyping and integration into circuits. The interfaces allow easy connection to sensors, displays and modules.
Software Compatibility
The XIAO SAMD21 is natively compatible with the Arduino IDE, giving access to a familiar ecosystem of libraries and examples. It also supports MicroPython and CircuitPython for alternative development and scripting approaches.
