SINGLE CHANNEL RELAY MODULE
This is a compact single-channel relay module PCB designed to control AC appliances using microcontrollers like Arduino or ESP32. I created it to offer a safer, cleaner, and more reliable alternative to bulky relay modules. It features a flyback diode, LED indicator, and screw terminals for easy use. The PCB ensures safe switching with optional optocoupler isolation. It's ideal for home automation and DIY IoT projects. I tested it by switching a light bulb using an ESP32, and it worked flawlessly. Simple, efficient, and perfect for embedded control systems
