Note:

Hey community! XIAO ESP32-C5 is available now!
Since our first production run is limited, we’re limiting purchases to 5 pcs per person so more developers can get boards for testing and development.
Plus, we’re inviting you to shape the XIAO Open Roadmaphelp us build better products together through open collaboration!

Seeed Studio XIAO ESP32-C5 the first XIAO module with 5 GHz Wi-Fi support, marking a new milestone in the XIAO family.

Built on the RISC-V architecture, it brings together 2.4 GHz and 5 GHz dual-band Wi-Fi 6, Bluetooth 5 (LE), and IEEE 802.15.4 (Zigbee, Thread)connectivity,while offering full support for IoT application protocols including Matter, HomeKit, and MQTT. With this versatile combination, your projects gain smoother, faster, and more reliable wireless performancer.

First Seeed Studio XIAO with 5 GHz WiFi

Provides dualband WiFi 6 for cleaner spectrum access and higher throughput in 5 GHz, while maintaining 2.4 GHz compatibility.

Comprehensive connectivity

Dualband WiFi 6, Bluetooth 5 LE, and IEEE 802.15.4 provide comprehensive IoT protocol coverage, with full support for Matter, HomeKit, and MQTT.

Highperformance core

Equipped with a 32bit RISCV singlecore processor running up to 240 MHz, the XIAO ESP32C5 integrates 384 KB onchip SRAM, 320 KB ROM, 8MB Flash, and 8MB PSRAM. This combination ensures smooth protocol handling, multitasking, and application scalability.

Enhanced security

Secure boot, flash encryption, and hardware cryptographic accelerators to protect firmware and data integrity.

Builtin Battery Interface for LowPower Designs

Integrated battery management supporting ultralowpower operation, with deepsleep current as low as 15A.

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.
