A part of the review has been auto-translated.
high quality relay I use it to turn on and off my 3d printer using Octoprint on a OrangePi zero. works flawless even with 5v GPIO output.....
They are great quality for the price. Test them with uno board and they work nicely.
bien normale ca fonctionne parfaitement bien attention au contacté entre les deux vis.
Looks fine. Have not tested them yet.
I did not have time to test. 1-2 minutes during operation is good. Price is good. Fast shipping. Good packaging. Injury-free.
nice
as described and works well
It is arrived 2 week later than expected delivery date, but in any case in compliance with the scheduled times. Each piece is individually packaged, so it is good to preserve.
