Seeed Studio XIAO RP2040 Microcontroller Board

The Seeed Studio XIAO RP2040 is a feature-packed, Arduino-compatible microcontroller board built around the powerful Raspberry Pi RP2040 chip. It combines high performance, an accessible price point, and remarkable ease of use in a footprint as small as a thumb (21x17.5mm), making it an ideal core for a vast range of compact electronics projects.

Powered by the RP2040's dual-core ARM Cortex M0+ processor, this board delivers robust computational power for demanding applications. Its ultra-compact form factor is specifically designed for wearable technology, portable gadgets, and space-constrained designs where every millimetre counts. The board's versatility is further enhanced by its broad software support, being fully compatible with the Arduino IDE, MicroPython, and CircuitPython, allowing developers to code in their preferred environment.

Key Features & Specifications

The XIAO RP2040 offers a comprehensive set of I/O to connect sensors, actuators, and displays. It provides 11 digital pins, 4 analogue inputs, and 11 PWM-capable pins for precise control. Communication is handled by dedicated interfaces including I2C, UART, and SPI, while a 1xSWD bonding pad interface enables easy programming and debugging. This rich I/O suite makes it perfectly suited for Internet of Things (IoT) nodes, interactive art installations, and advanced applications like on-device TinyML (micro machine learning).

Designed for prototyping convenience, the board features a breadboard-friendly SMD design with pre-soldered headers, allowing for quick integration into circuits without specialised soldering equipment. Its combination of raw power, tiny size, and developer-friendly ecosystem makes the Seeed Studio XIAO RP2040 a standout choice for students, hobbyists, and professional engineers looking to create the next generation of smart, connected devices.
