Description The M5Stack Module13.2 2Relay is a dual-channel relay module with an onboard STM32F030F4P6 controller and I2C bus communication. It provides two relay outputs for compact circuit switching while saving host IO resources in M5Stack projects. Each channel is designed for relay-based load switching, with AC/DC electrical characteristics and AgSnO2 contact material. The module is suitable for on/off control, solenoid valve control, DC load switching, and remote IoT switching applications. Notes Load rating: Each relay channel supports up to 250 VAC at 5 A. Match the connected load and wiring to the official rating before use. Power input: The module supports AC/DC input and uses I2C communication at address 0x26. Features Dual-channel relay module with onboard STM32F030F4P6 controller. I2C communication at address 0x26. 2 relay channels for AC/DC load switching. Supports up to 250 VAC at 5 A per channel. Power input supports AC/DC input. Compatible with Arduino and UIFlow programming platforms.
