Production-Ready Design with Fusion PCBA Support

All Seeed Studio XIAO dev boards feature a production-optimized SMD (Surface Mount Device) design with standardized stamp holes, making it perfect for commercial PCBA (Printed Circuit Board Assembly) integration. Through our Fusion PCBA Sponsorship program, you can not only enjoy the lowest unit prices for all XIAO modules from our Fusion Open Parts Library, but also fabricate and scale your XIAO-based PCBA designs at low cost (30% off) with FREE Design for Manufacturing consulting services, streamlining your journey from prototype to production.

To better support IoT and TinyML AI projects, there is an advanced version "Seeed Studio XIAO nRF52840 Sense" that is equipped with a 6-axis IMU and a PDM Microphone onbaord.

Attention:

All I/O pins operate at 3.3V. Please ensure not to input more than 3.3V to avoid damaging the CPU.
