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.

Features:

• First Seeed Studio XIAO with 5 GHz Wi‑Fi

Provides dual‑band Wi‑Fi 6 for cleaner spectrum access and higher throughput in 5 GHz, while maintaining 2.4 GHz compatibility.

• Comprehensive connectivity

Dual‑band Wi‑Fi 6, Bluetooth 5 LE, and IEEE 802.15.4 provide comprehensive IoT protocol coverage, with full support for Matter, HomeKit, and MQTT.

• High‑performance core

Equipped with a 32‑bit RISC‑V single‑core processor running up to 240 MHz, the XIAO ESP32‑C5 integrates 384 KB on‑chip 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.

• Built‑in Battery Interface for Low‑Power Designs

Integrated battery management supporting ultra‑low‑power operation, with deep‑sleep current as low as 15 µA.

Unlock the Full Potential of XIAO with Add-ons

The XIAO series is powerful on its own, but it becomes unstoppable when paired with our diverse lineup of Add-on boards. Designed to bridge the gap between a raw microcontroller and a finished project, these add-ons cater to every need: from XIAO Expansion Board—which adds an OLED screen, RTC, and battery management—to specialized functional modules like Wi-Fi HaLow and LoRa (SX1262) for long-range connectivity, LED Driver Board/COB LED Driver Board for lighting applications, or ePaper Driver Boards compatible with various display sizes for ultra-low power visual interfaces. Dive into our extensive modules to discover even more ways to expand your XIAO.

We already have over 15 XIAO products based on different solutions in the XIAO family, to help you better understand the differences and choose the most suitable part for your projects, please refer to the Seeed Studio XIAO Series Page.
