Ahahah this one seller sent two of a kind and one of another, they don’t match and I believe there’s even a Typo on the middle one markings ! All three don’t match the pics in the eBay listing ... no replaceable battery ... oh well ... ;) https://www.flickr.com/gp/danielnogueira78/Ga3UTA and https://www.flickr.com/gp/danielnogueira78/wKN83a</p>

By any chance you could get some FYQ-3942BUA ? I believe these are Amber instead of yellow ... I’m preparing a car project and I need Amber to match the dashboard lights on my Renault Clio =)</p>

If you are looking at a different data sheet showing other information, please let me know where you found it, so we can get that updated. We don't want anyone confused on this!</p>

<a href="http://optoelectronics.liteon.com/en-us/product/detail.aspx?txtSpecNo=DS30-2000-196&txtPartNo=LTC-4727JS" rel="nofollow">LTC-4727JS</a>. On the datasheet and on the Lite-ON site, this display is shown as common cathode rather than common-anode as Sparkfun indicates above.<p>So, either this is the wrong datasheet for what SF is actually selling, or their product description is wrong. I suppose both could be wrong, but how to tell? Here's two options: 1) Since I want to buy a few of these for a project (SF actually sells them cheaper than Mouser) I could find out empirically whether they're common anode or cathode. I can use either one, but I do need to know which is which. I can then report back here for future seekers of truth --OR-- 2) Sparkfun can straighten this out themselves. Either way, from the older comments above, this has been a matter of confusion for years. Frankly, I'm a little surprised.</p></p>

The L3 is also used as a clock function to show AM or PM if a 12 hour clock. Of course these can be anything the programmer wants.</p>

They're the colon and the odd one between the last two digits (anyone know what that's for?)</p>

I don't think its to keep the wires from falling out, correct gauge wire should hold well in a breadboard. It also might be due to obsessive compulsions, notice the blue wire at the top right corner of the image is bent at the right as it was slightly longer than needed!</p>

So the pins labled "Digit 1, Digit 2..." are the common anodes.</p>

Is that so they stay in and don't fall out as easily? It's bugging me... makes me feel as if I do it wrong...</p>

I'm hoping that those pins (14,15,16) are N/C's because in my design i'll need to cut them off, i'm just wanting to confirm before i send off my board designs.</p>

Both displays are the exact same size. The footprints are similar (same pin-spacing), however this display has all 16-pins connected (and a function for each pin), rather than the 14 on the older display.</em><br>
If so, what are the functions for pins 14 to 16? Datasheet only covers pins 1 to 13.</p>
