Great relay boards with smart design
I'm surprised there are no reviews for KANCRO Relay boards, considering how fast they are running out of stock. After lot of research and experiments, I found these and never regret. On DC side, they have full opto-isolation between control and actuator circuits (with separate ground terminals). This allows very little power draw on control side and they can be directly connected to GPIO ports. Also, unlike many other boards, 3.3v supply for control voltage is not a problem. I'm using 12v actuator version and it draws around 70mA per relay. Yes, they have "click" sound while switching, but in my setup, this is not critical. Keep in mind, that unlike induction ones, not all trendy solid state relays have proper isolation between AC and DC side.and here comes WARNING - I never tested them for 30A and not sure PCB paths for AC are suitable for that current continuously, but 10-15A 220V, that's usual peak rating per Cirquit Breaker (MCB) in regular household, they take with no problem.
