Highlights
Quality
It is an amazing power relay board, fits well on the raspberry pi mother board.
Works great as a power switch under control of a raspberry pi 4.
So it's controlling a 12 vdc linear actuator.
Shipping
Received the product on time and works great with my pi 3.
Competitiveness
I did get webiopi to work with an older raspian os release, but not with modern ones.
