M5Stack 2-Channel AC Relay Module 13.2

M5Stack 2-Channel AC Relay Module 13.2 – Reliable AC Switching Control for Your Project

The M5Stack 2-Channel AC Relay Module 13.2 is a compact expansion module for the M5Stack ecosystem. It allows independent control of two AC loads and is ideal for home automation, IoT prototypes, and industrial switching tasks.

• Control two AC devices simultaneously – perfect for lighting or small motors in your automation projects.
• The integrated STM32F030 microcontroller ensures precise signal processing and reliable switching operations.
• Compact design – the module fits seamlessly into your M5Stack stack, saving valuable space.
• Compatible with all M5Stack cores – simple plug-in without additional wiring.
• 24-month manufacturer warranty ensures long-term investment security.

What sets the M5Stack 2-Channel AC Relay Module apart

Unlike simple relay modules, this board offers direct integration into the M5Stack architecture. The interface to the STM32 chip enables programmable logic – you can flexibly adjust switching times, delays, or sequences without external components.

Ideal for...

The module is aimed at makers, electronics developers, and IoT engineers who need to integrate AC loads into their projects. Whether for smart home controls, lab setups, or industrial control cabinets – it provides a processor-driven solution for recurring switching tasks.

How to use the M5Stack 2-Channel AC Relay Module

Plug the module onto an M5Stack core (e.g., M5Stack Basic or Core2). Connect the AC devices to the relay outputs (max. 25 V AC). Program the switching logic using the M5Stack development environment (Arduino, UIFlow). The module is powered by the core – no separate power supply needed. Test the switching function with a simple on/off script before connecting the end devices.
