produit conforme et de bonne facture

Easy to use. Can be use high volatge. Very usefull modul. Quality is very well. Three LEDs is good to check if it is function.

For my automated fireplace temperature control with an arduino nano and ventilators I use these relays to shut off the ventilators if the pulse modulation is zero to hard switch them off. Pros: two channel, nice click Cons: four channels are almost cheaper per channel.

Con esta PCB de relés se pueden hacer realidad los proyectos de potencia con arduino. Sólo necesita 5V Gnd y el input de 5V para activar el relé 1 o relé 2.
