FTCBlock 5V Relay Module with Indicator Light with Optoupler for Arduino Ras Pi (1 Channel, DC 5V)

Used with an arduino - computer interface to control a powered wheel chair with eye movements. Worked flawlessly

Good quality relay bank.I can easy operate heavier and different loads with a very basic exterior wiring to independent switches

It is good enough for my application. Easy to connect.

great board you can have the relays either sinking or sourcing individually. they have led indicators on each relay to show when they are powered up.

I have used these relays several times including automotive switching needs and they are great. Compact size and good quality. Well worth the price.

Works as described, low cost

Works like a charm in my raspberry project for more than 3 month

Mine showed up using pin connections instead of screw terminals. Not worth the hassle of returning but created an additional expense.
