    7 Segment Display Help.

    Hi,

    I have just ordered 3 of the FS-BUS 7 segment display PCB's for my NAV/COM radio and would like to know if anyone has got the displays pieces to go in it.

    I need 14 of them and has been quoted 17 + 12 shipping. 12 Shipping is a lot of money for just 14 tiny displays (the size of a penny each!)

    So, if anyone has any spare that they could sell me, then please let me know and I will buy them with no questions asked.

    Looking for these little fella's:

    Anyone know of a supplier of these that wont rip me off for 12 on the shipping?

    Kind Regards,

    Alex

    I have 12, 7segment displays but they have amber numbers, they measure 12mm x 8mm and need de-soldering from an old pcb if they are any use you can have them.

    Re: 7 Segment Display Help.

    Alex,

    Looking at the specs for these displays vs the ones that OC sells (Avago HDSP-7403), it looks like the width of each display is different. The Kingbright is 7.5 wide and the Avago displays are 7.62 wide.. this might be enough to make them look too far spaced from each other... I dunno.... it's close.

    The other thing to watch of course is that you get displays that are common cathode.

    The Mouser link to the Avago displays is here:

    Re: 7 Segment Display Help.

    Thanks guys, what I am concerned with is making sure that the pins fit the board exactly, so what displays do I exactly need to fit the FS-BUS display pcb's?, these are not the OC boards, I am guessing that the fs-bus pcb's are pretty much the same as OC pcb's, both do the same thing I guess.

    Hmmmm, I'm a little lost, maybe I should take a photo of the boards when they arrive, and then maybe you guys can give a verdict?

    Cheers,

    Alex.....

    Re: 7 Segment Display Help.

    Can FS-BUS PCB's be used on OC display boards?

    Also, the OC manual for the display card shows only how to wire ONE display card to the board, I am very puzzled to how you wire up THREE boards to the OC display board.

    I have 2 x PCB's @ 5 digits
    I have 1 x PCB @ 4 digits

    Total 14 digits which is within the maximum digits available (which is 16) on the OC displays card.

    Can anyone offer me any assistance?

    Kind Regards,

    Alex

    Alex,

    If you are referring to connecting multiple seven-segment display holders to a singe displays driver card, you have to come up with a distribution point. I built a header board with a bunch of segment pins in parallel, then a header row with a pin for each digit. I had a pic posted here but I think it's gone, lemme look for it..

    Re: 7 Segment Display Help.

    Many thanks for that buddy.

    I guess I can make a distro-board just using a spare piece of perf board or vero board......

    Thanks for the diagram, I knew it would be something similar to this, you have just confirmed it!

    Many thanks again,

    Again!
