The 4 Channel Relay Board for ESP32 30 Pin 5V Module is a ready-to-use control module designed for reliable switching of multiple AC or DC loads using an ESP32 development board. Featuring four independent relay channels, this board allows ESP32 users to control high-power devices, home automation systems, or DIY electronics projects safely and efficiently. Operating on a 5V DC supply, the board is fully compatible with 30-pin ESP32 modules and provides convenient pin headers for direct interfacing. Each relay channel can be triggered individually from the ESP32 GPIO pins for precise control over connected devices.

Features:

1. 4-channel relay output for independent load control
2. Compatible with 30-pin ESP32 development boards
3. 5V DC operating voltage
4. Supports AC and DC load switching (relay rating dependent)
5. Stable and reliable relay operation
6. Easy GPIO-based control via ESP32
7. Compact PCB size: 80x68mm for convenient installation
8. Ideal for home automation, industrial control, and DIY electronics projects
