8 Channel Relay Module compatible with Raspberry Pi and for Raspberry Pi Pico, Optocoupler Isolated Relay Expansion Board, 5-12V Wide Voltage Input, GPIO Jumper Select, LED Status

🍓 8 Channel Relay Module / 8CH Relay Board – 8-channel relay expansion board with eight independent relays for precise ON/OFF control; ideal relay module for automation, robotics, test rigs, and DIY projects.
🛡️ Optocoupler Isolated Relay Expansion Board – Onboard optocoupler isolation helps reduce interference from the load side and adds protection for the controller side, improving stability for an 8 channel relay module setup.
⚡ 5–12V Wide Voltage Input + Protection – Supports 5-12V wide voltage input for flexible power options; includes 5V output short-circuit protection to help safeguard your relay board and connected devices during development.
🔧 GPIO Jumper Select, Custom Pin Mapping – Unlike fixed-pin relay hats, this relay expansion board uses GPIO jumper selection so you can assign custom GPIO pins per channel to fit your wiring and code.
💡 LED Status Indicators + Compatible with Raspberry Pi – Each channel has an LED status indicator for real-time feedbac
