XIAO 6-Channel Wi-Fi 5V DC Relay
Overview
The XIAO 6-Channel Wi-Fi 5V DC Relay is a compact automation controller built on the XIAO ESP32-C6 platform. Designed for Home Assistant via ESPHome, it enables reliable control of up to six DC loads with full Wi-Fi integration. Ideal for smart home, small automation panels, and maker projects requiring a low-voltage relay module with expandable I/O options.
Key Features
• Pre-installed ESPHome for instant Home Assistant integration
• Six independent relay channels (COM / NO / NC per channel)
• XIAO ESP32-C6 for stable Wi-Fi 6, BLE 5.0, Zigbee & Thread capability
• Grove I²C and UART ports for sensor/actuator expansion
• USB-C powered XIAO module for firmware updates and custom development
• Supports Arduino IDE for full programmability
• Compact 3D-printed enclosure included (Early Build edition)
Note:
“Early Build” units ship with a 3D-printed case and evolving firmware.
