Product Description

Overview Upgrade your automation and control projects with this 8 Channel Relay Board—an optocoupler isolated relay module built as a versatile relay expansion board for makers and developers. With eight independently controlled channels, this 8CH relay module enables accurate ON/OFF switching for a wide range of low-voltage control applications such as smart home prototypes, robotics, industrial test fixtures, and IoT demonstrations. Stable design with isolation: The onboard optocoupler isolation helps minimize interference transferred from the load side, improving signal integrity and reducing unexpected triggering in complex wiring environments. A 5-12V wide voltage input makes the board adaptable to different power supplies, and the onboard 5V output includes short-circuit protection to help safeguard your setup during prototyping. Flexible pin mapping: Unlike fixed-pin relay hats, this GPIO jumper select relay expansion board allows you to choose and route control pins based on your project needs—helpful when certain GPIOs are already occupied or when you want consistent wiring across multiple builds. Each channel includes a bright LED indicator so you can instantly confirm relay states during debugging. Platform fit: The board layout is designed compatible with Raspberry Pi 40-pin GPIO header systems and compatible with Raspberry Pi Pico development workflows, making it easy to integrate into popular maker ecosystems. Note: This is a development accessory for switching loads. Use suitable enclosures, correct wiring, and follow local electrical safety requirements. Always operate within the relay contact ratings printed on the product. Package Contents 1. 8-CH Relay Borad x1 2. Case x1 3. Screws pack x1
