The 4 Channel Relay Board for 38-Pin ESP32 (5V, 4CH, 80x68mm) is a ready-to-use control module designed for safe and reliable switching of multiple AC or DC loads using an ESP32 development board. Featuring four independent relay channels, this board enables ESP32 users to control home automation devices, industrial equipment, or DIY electronics projects efficiently. Operating on a 5V DC supply, the board is fully compatible with 38-pin ESP32 modules and provides convenient pin headers for direct interfacing. Each relay channel can be individually triggered via the ESP32 GPIO pins for precise control over connected devices.

Features:

1. 4-channel relay output for independent load control
2. Compatible with 38-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 easy installation
8. Ideal for home automation, industrial control, and DIY electronics projects
