Seeed XIAO ESP32C5

The XIAO ESP32-C5 is a compact dev board with dual-band Wi-Fi 6, Bluetooth LE, and Zigbee/Thread support for fast, flexible IoT connectivity.

The Seeed XIAO ESP32-C5 is a compact wireless development board that brings dual-band Wi-Fi 6 and multi-protocol connectivity to the XIAO range. Built on a RISC-V architecture, it supports both 2.4GHz and 5GHz Wi-Fi 6, offering faster and more reliable wireless performance compared to previous XIAO modules. Alongside Wi-Fi, it includes Bluetooth 5 (LE) and IEEE 802.15.4 support, enabling Zigbee and Thread connectivity for low-power mesh networking. This combination of wireless options makes it well suited to modern IoT applications, with support for popular protocols such as Matter, HomeKit, and MQTT. Whether you're building smart home devices or connected sensors, it provides a flexible platform in a very small form factor.

Features
