I used this as an add-on to my garage door opener because I wanted a tiny remote for my bike.It says 12v, and I used a 9V supply on it with no issues.Range is incredible.It comes with the relay set up as latched.
But was very easy to program.Manual is extensive in every language.I unwound the antenna on the inside and made it straight. Amazing range, as I said.Code learning worked well.Great find
