functional diagram of Sun Harvester Shield V2
« on: September 06, 2015, 06:33:24 AM »
Hi,

I am considering to purchase one of your "Sun Harvester Shield V2" boards, and would prefer to know more about it before I purchase.

Do you supply a functional diagram or schematic with the purchase?

I have looked at the "Sun Harvester Shield V2 Source" in particular the PCB layout and before I reverse engineer it, wanted to give you the opportunity to supply this information.

I am not looking for a schematic that I can use to copy the board.
I am wanting to understand what pin of the shield connects to what component on the shield.
For example below is an image suggesting the information I am wanting.

I want to know if the PBs and SWs use pull-up or pull-down, what LED I can control from what pin, and how you have implemented the RTC and I/O expander functionality.

From reading the datasheets of the RTC and I/O Expander ICs, and the PCB layout in Design Spark, I could gain an understanding of the circuit, and produce my own functional diagram...

So, can you please provide a functional diagram or similar?
Thanks,
Ben.

Hi Ben,

I have a sort of diagram at this link.
http://www.cerebralmeltdown.com/wp-content/uploads//2012/07/SunTrackerCircuit3_bb.pdf

I've never actually gotten around to makeing a proper schematic, but the above link says which pin goes where.

Is that what you are looking for?

Sorry about the delayed reply.

Gabriel

Hi Gabriel,

Thanks for that link above, it does take me to a PDF showing a layout similar to what im after.

I notice that the PDF shows separate driver boards, whereas now you supply a single driver board that controls both AL and AZ steppers. In this regard, I think an updated diagram would be good.

If you dont mind, I could post a diagram that I consider more helpful (at least to me), and could you please verify it for correctness?

Ben,.

Sure if you want. This diagram was made before the Sun Harvester Driver board existed, which is why it's not on it. There are other diagrams with it, but they all show it connected to the shield. This diagram is more of an example of how you would connect a driver board other than the Sun Harvester Shield I suppose.

Attached below is Version 1 of the diagram.

- is incomplete
- needs LED shown
- needs D13,D14,D15 connected

Hi Gabriel,

Thanks for your feedback.
Yes I will modify based on your comments made via email.

Can you please advise what needs to go in the title-block?
ie the copyright info...,
And do you want anything more than what is in the titleblock?

Ben.
