1-Channel Relay for Seeed Studio XIAO is a single-channel 5V relay expansion board built for seamless integration with any XIAO development board. Featuring the HF32FA-G relay, it brings reliable switching capability to IoT and home automation projects without needing a separate relay module wired up externally.

High Electrical Performance

The HF32FA-G relay supports switching loads of up to 10A at 250VAC, giving it enough headroom for controlling household appliances, lighting circuits, and other higher-current loads directly from a XIAO board.

Seamless XIAO Integration

Designed specifically to plug into the Seeed Studio XIAO series, the board is ready to go without extra wiring or adapters, saving setup time for smart home, automation, and other DIY relay-switching projects.

Compact and Efficient Design

At 21 x 42mm, the board keeps a compact footprint that suits space-limited projects, while still housing a relay rated for a long working life of 100,000 cycles.
