Thanks, my board arrived today. Now to get the rest of the items to convert my manual system to an automated one.

Can setup the board and Pi without actually connecting any of the channels?

No reason why you can't have it running on your desk. will work just fine like that.

Hi ALL

I have decided to work with smartkit regarding the sales and stocking of these boards.

So any stock availability questions and sales questions should be directed to them.

I will try my best to answer technical questions and by all means keep posting them and your photos and your installs in this thread.

My own board has been running for more than 3 years 24/7.

Through smartkit there will also be made available extra options , including IP rated enclosures etc.

Obviously this WILL include extra costs including VAT etc.

The cost at which I was providing these with the small production runs was never going to be a sustainable model time wise for me especially , taking into account packaging etc etc.

I will not be able to supply these at a cheaper cost than Smartkit ,please don't ask. :)

Nope, the amps are too low, you need at least 2A @24VAC min. Buy the correct transformer at any irrigation house.

Depending on which pi you use you need around 0.5 to 1.5 amps for the pi. Remember the pi runs on 5v. You could easily for testing purposes run the board with just the pi on 16v AC. (Not DC). Solenoids all run on 24vac so you should get 24vac transformer for the final product. You could easily run a system including 1 solinoid at a time with a 1 amp. 24vac transformer.

 If that transformer is AC you could bench test it with it. It just has too low voltage for irrigation taps.

Never power the pi from micro usb while plugged into the board. Board supplies pi with 5v from AC input

That one is only 12v you need 24v AC.
25VAP-24-T. Would be the one

Ah yes, I linked to the wrong one. That's the one I have.

I'm assuming the wiring from the terminal block is like lamp wiring? Ie. Live/neutral or pos/neg?

It is isolated AC. So technically no neutral or live. Polarity doesn't matter.

On the RPi power supplies.

-The RPi A/B/B+ all use the 5V /2A power supply units. Obviously, if you have extra boards attached to the RPi, like a HAT, you would need more current supplied. I'm currently using my RPi B with a hifi-berry dac running off the 5V/3A power supply.
-From the RPi 3B/B+ you require the 5.1V/2A power supply units. -Here I would recommend buying the original RPi power supply, because of the voltage difference. I bought a 5V/3A power supply unit for my RPi and works, but gives the low voltage square when you run the RPi 3. Not a problem, as per say, just irritating.

-Hope this helps.
