A part of the review has been auto-translated.
goed quality and very fast delivery. bought it with a nice discount. and i woud recommend it for everton to buy of you need it. online minor thing is the packaging. this could be beter. on one board there was a pin a little bit bend. but overall great quality and great service. i will buy it again of needed
Clean construction, all relays fully functional. I tested with line voltage (230V) and all relays switched. Arduino interfacing was trivial. Good quality
Very well mounted and finished. It will allow Very good automation. Good price.
working perfectly
I haven't yet tested the device but about packaging I must say it was not good enough. Pins were bent.
nice circuit with 8 relays; the relays are insulated with a photo coupler and there is a LED for signalling the active channel. The command is active low. Mine PCB arrived with some bented pin on the main connector, but it was easy to solve with a plier and some patience. satisfied circuito con 8 relè comandati da foto isolatore; c'è un LED per segnalare i canali attivi. il comando è attivo basso. il mio PCB aveva alcuni contatti pin piegati, ma ho risolto facilmente con una pinza e un pò di attenzione. soddisfatto
It arrived look like the shippers were a little rough on the package and bent some pins but no damage it all works great. I connected it to my K8055RS USB experiment interface board. Working right away no fiddling or troubleshooting.
Calidad-precio excelente, tiene transistores para activar los relés mediante un microcontrolador. por el precio de 1 relé en españa , aqui tienes 8!!! 100% recomendable
I use it with an arduino LoRa board to control my automatic watering system in the garden. Works flawlessly. I recommend
Perfect
