1. Product Introduction
8-CH Relay, Relay Expansion Board, Compatible with Raspberry Pi / Raspberry Pi Pico
This 8-channel relay expansion board is designed for the Raspberry Pi / Raspberry Pi Pico series. It features a Raspberry Pi 40-pin GPIO header, making it suitable for Raspberry Pi mainboards and offering excellent versatility across multiple Raspberry Pi platforms. The board includes eight high-quality relays, each independently controllable, enabling precise ON/OFF switching of connected devices, making it ideal for home automation, robotics, and other IoT applications.
Key advantages:
· Onboard optocoupler isolation for strong immunity against high-voltage interference, protecting your Raspberry Pi
· Flexible and easy-to-use GPIO assignment via jumpers, adaptable to different programming needs
· Wide input voltage support (5-12V), plus short-circuit protection on the 5V output to protect your equipment
· Open-source support with demo code and technical support for faster troubleshooting
2. Product Features
· Wide voltage input: supports 5-12V input
· Isolation protection: optocoupler isolation helps protect the board from high-voltage circuit interference, ensuring stable and safe operation in harsh environments
· Relay load rating: AC 125V/12A, AC 250V/10A, AC 277V/10A, DC 28V/5A
· Clear working status: each relay includes an LED status indicator for real-time visual feedback
· Customizable control: relay control jumpers allow you to assign custom GPIO pins instead of fixed default settings
