I have a common anode seven segment display, how do I find out it's pin specifications.Nothing is mentioned (product name or number ) on it.

    \$\begingroup\$ We have even less to go on, since there's not even a picture in your post. Probably you will just have to guess. \$\endgroup\$ – Phil Frost Jul 4 '13 at 18:17

    \$\begingroup\$ It won't take too long to set up a suitable power supply and resistor and just try combinations of pins until you find the anode, then map out the segments 1 by 1. \$\endgroup\$ – pjc50 Jul 4 '13 at 18:48
  • \$\begingroup\$ Most of those have pretty standard pinouts - post a link to a picture if you cannot post a picture yourself and someone will add it. Otherwise, just take a 5V supply and a 1k resistor and play around with it. \$\endgroup\$ – Kurt E. Clothier Jul 4 '13 at 19:27

    \$\begingroup\$ (1) Too localized. Deals with a specific commodity part. (2) Insufficient preliminary research. \$\endgroup\$ – Nick Alexeev Jul 4 '13 at 20:10
  • \$\begingroup\$ If that picture is the component in question it definitely does have a manufacturer (HP) and number (HDSP 5301, if I read it correctly) on it. If it is not, please post a picture of the correct part! \$\endgroup\$ – Wouter van Ooijen Jul 4 '13 at 21:31

So here's what I've done.

  1. I noticed that your image says www.allspectrum.com on it, so I went to that website.
  2. There, I searched for "display", and I looked in the first 20 results.
  3. Not surprisingly, I found a link to the product.
  4. On that webpage, I found a link to the datasheet, which should have everything you need.
