New build.

[Christopher Kindig]

new ISO board build, designed by Fernando.
Board printed by OSHpark.com.
Board built by Christopher Kindig. (with help)
It connects to the stamps and pins 14,15,16,17 to isolate power to each stamp and make the readings stable.
More common used when using EC probe.

this is one of my favorite parts of the tank, green zoanthid colony, my hammer coral and, a small blue berry patch corral.

Hi Fernando can 12 volt be applied to the brown and brown and white wires with out damage to the board?

[Fernando Garcia]

Hi!

Yes, but I can see a good reason for it. Mainly because there no GND in RJ45.

The VIN is connected on 5V regulator so, is better use power jack directly.

Best regards.

[Christopher Kindig]

Okay so it would not matter to get 6 volt pumps as the board will not power them?

[Fernando Garcia]

Hi!

I don't understand.

Using 12V in power jack you will get this voltage in RJ45 so, using 6V in power jack you will get this voltage in RJ45 too and so on.

Best regards.

[Christopher Kindig]

Do you mean the main power jack, 5.5mm barrel jack?

[Fernando Garcia]

It's 2.5 / 5.5 mm.

Yes okay, but that is where you are saying to apply 12v and I will have 12v available on other components like the dosing pumps?

If you have the board powered with 12V, this voltage will be available on connector DB25 on pins called V = VIN. You can use this 12V to supply the relay board.

Hi Fernando, I went back and checked all of talks saw that, I am going to try it today with the old board and verify that does what I need it to do. I did check the voltage and it goes through at 12.8 volts should be okay.

[Christopher Kindig]

as soon as I connect 12v too the board I lose network.

[Christopher Kindig]

connected to live controller and is working with 6.5 volt and network is stable.

[Fernando Garcia]

Hi!

Are you using a fan to cooling the heatsink?

Best regards.

[Christopher Kindig]

Not at the moment, why do you ask?

[Fernando Garcia]

Hi!

Because it's important when using more than 9V.

Best regards.

[Christopher Kindig]

I am not using 12v on the board, when I do it causes the network issues we have been talking about.

[Fernando Garcia]

When you was testing with 12V power supply, you was using a fan to cooling the heatsink and regulator?

[Christopher Kindig]

Yes and even then the network issue started right away, have you completed a board for the wave makers yet?

[Fernando Garcia]

Hi!

It's strange because I did test using 12V on this board without any issue.

I have the project for Jebao pumps, you can see here: viewtopic.php?f=24&t=40

Best regards.

[Christopher Kindig]

what I was asking is if you have made a board or done any testing yet.
