Reef Angel Forum

Fatman, you are perfectly right. I thought the JP1 connector from the schematic posted by Sacohen was a jumper. Too fast analysis by myself. Thank you for your explanation. It got perfectly clear. Thank you!!

Oh, ok! I see there is a jumper at the cabe which enables a voltage divider working at 50%, so I just have to close the jumper to make PWM level work at 50%?

A simple question came into my mind: reef angel PWM level is 10v. Is it possible to drive these pumps with 5v pwm level?

Thank you very much, people!

Oh, didn't know that. Thanks for the explanation. Now tell men will this connector fit?

They look like the same, but the first is 0.3mm2 and the second is 0.75mm2.

Is the Jebao connector an ordinary female circular connector aka MIKE connector?

It's much easier to build them with independent circuits than together in one circuit. They need galvanic isolation or they would interfere with each other. The components to isolate the two circuits would cost even more than building them separate. I see the ORP module, as the Salinity one, is dri...
