8 Channel Relay Modules 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 Modules / 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 feedback; designed for Raspberry Pi 40-pin GPIO header and compatible with Raspberry Pi Pico for easy integration.
