Feature
Note:
We are introducing a new more durable packaging for all Seeed Studio XIAO boards (Un-Soldered, Pre-Soldered and Plus). During the transition period , you may receive XIAO boards in either the current or new packaging, while the product quality remains identical. Thanks for your understanding.

- Perfect Toolset for Learning Coding and Electronics
XIAO RP2040 offers an extensive development ecosystem that makes coding accessible for beginners while providing powerful tools for experienced developers. Code with Arduino IDE for rapid prototyping, utilize C/C++ SDK for optimal performance, explore MicroPython/CircuitPython for quick scripting, or develop with Rust and Go for modern applications. Backed by comprehensive documentation and an active Raspberry Pi community, you'll find abundant examples and resources to kickstart your projects. The board features both a 3-color User LED and an RGB LED, making it easy to add visual indicators or stunning light effects to enhance both functionality and creativity.
- Solder-Free for Instant Creation
The pre-soldered headers mean you can start creating immediately - just unbox and plug into your breadboard. No soldering iron, no waiting, no hassle. Perfect for rapid prototyping, educational workshops, beginner-friendly projects, and time-sensitive development. Because great ideas shouldn't wait for solder to cool.
- Classic Form Factor and Extensive Seeed Studio XIAO Ecosystem
Launched in 2021, XIAO RP2040 with the classic XIAO compact design of 21 x 17.8mm. Its native compatibility with the comprehensive XIAO Add-on ecosystem - from expansion boards, sensors and displays to connectivity modules and actuators (Grove Expansion, CAN-Bus, LoRa module, LED Matrix, Vision AI Sensor, Round Display, L76K GSP module, 2-Mic Array, ePaper Displays, mmWave sensor, AC relay, Bus Servo Driver and many more) - makes it versatile for any project, no matter how simple or complex.
