Seeed Studio XIAO ESP32-C5 with 2.4/5 GHz Dual-Band Wi-Fi 6, Bluetooth LE, Zigbee, Thread and Matter
The Seeed Studio XIAO ESP32-C5 is a compact wireless microcontroller board designed for IoT, smart-home, gateway, and battery-powered embedded applications. It is the first XIAO board to support 5 GHz Wi-Fi, combining 2.4 GHz and 5 GHz dual-band Wi-Fi 6 with Bluetooth 5 Low Energy and IEEE 802.15.4 connectivity. This multi-radio architecture supports Zigbee and Thread while enabling development with application protocols and ecosystems including Matter, HomeKit, and MQTT.
Powered by a 32-bit RISC-V processor running at up to 240 MHz, the XIAO ESP32-C5 includes 384 KB on-chip SRAM, 320 KB ROM, 8 MB Flash, and 8 MB PSRAM for connected applications requiring larger buffers and more complex protocol stacks. Its compact 21 x 17.8 mm XIAO form factor, USB Type-C connectivity, lithium-battery management, external U.FL antenna support, and deep-sleep current as low as approximately 15 uA make it suitable for compact wireless devices, smart sensors, gateways, wearables, and secure edge systems.
