5V 12V 24V Relay High Low Level Optocoupler Board Module 1-2-4-6-8 Pi Channel

This unbranded relay comes with a clear plastic cover, so dust stays out and you see the internals easily.

What stands out about the unbranded brand is the lack of logos, keeping the look consistent with other anonymous hardware.

I like that the indicator light stays visible without being harsh or distracting during long runs.
