Falcon F3 or F4 board pictures please?

[OldMarty]

Hi All,

If anyone has a Falcon (V3 or V4) controller board laying around, can you please take some close-up photos of the underside of the board for me? mainly around the pixel output connectors.

Thanks in advance.

Hello,

I was actually working on one when I read this. Hope these helps.

Hi Dean,

Thanks so much for doing that, greatly appreciated.

Is the heavy solder (soder) on the main power tracks something that you've added yourself? or is that standard "out of the box"?

Also, do you know if the data pins on each pixel output connector are simply all bussed together and being driven by one data-driver chip? or is each pixel output data driven by it's own data-driver chip? (16 driver chips).

I guess if you multimeter those little bare gold pads between 2 or more pixel output connectors, that will confirm that they're all bussed together (or not).

Thanks in advance.

Everything is stock out of the box. I've since mounted the board into a controller box and currently do not have access to the back of it for the time being.

No problems, thanks anyway ;-)

Pixel controllers all have separate data lines from the micro / CPLD / etc to each output port. This is often via a logic buffer IC and series resistors to limit the slew rate a little.

Thanks David,

Yeh, i wasn't quite sure if there were 16 different data streams to independently control each pixel string.

I guess this way makes sense to send unique data to each of the 16 pixel strings compared to just 1 buffered stream feeding all 16 pixel strings.

Thanks for confirming.

May I ask why you are asking? Is your board not performing as it should or requires repair?

No, nothing like that, i don't own a board, but curious to see the power bussing on the underside for a discussion on power distribution i'll be starting later.
