Waveshare Industrial 8-Channel Relay Module for Raspberry Pi Pico, Multi Protection

Eight independent relay channels give an automation build real headroom to control multiple loads from one module rather than running out of switching points partway through a project. Built specifically for the Raspberry Pi Pico's footprint and GPIO layout, it drops onto that board without needing a custom wiring harness, and the multi-protection circuitry guards against the common failure modes of relay-driven loads - inductive kickback from motors or solenoids, overcurrent, and similar faults that can otherwise damage the module or the controlling microcontroller over time. A solid choice for a Pico-based home automation, irrigation control, or similar multi-channel switching project.
