Description: Ever hear of a thing called RGB? Red, Green, Blue? How about an RGB LED? These 5mm units have four pins: one for each color and a common anode. Use this one LED for three status indicators or pulse width modulate all three and get mixed colors!
Note: The datasheet below is for the common cathode version of these LEDs, all of the values are the same except that instead of sharing a cathode, these share an anode. An updated datasheet will be added as soon as possible.
Features:
- Forward Voltage (RGB): (2.0, 3.2, 3.2)V
- Luminosity (RGB): (800, 4000, 900)mcd

Can anyone tell me which pin on the data sheet corresponds to which color? Thanks.
I’ve uploaded the latest library, but still, the pads on the library look like they overlap. Shouldn’t this show up correctly with the new library? When I import the part, the pads look correct.
In bypassing with ‘restring’ to you set min, max, or % to 0? I set % to 0, and things seemed to pass, but it seems like a kludge. Anyone find out what actually is wrong?
I’ve tried uploading this to Oshpark (when not overriding restring), to see what it says, and no errors show up, but I don’t know if Oshpark checks things again. I’m not sure if the clearances are OK. Oshpark’s rules say there is 6 mil spacing.
The datasheet that’s linked to currently looks like it’s for the correct (common anode) LED. Is the note in the description out of date?
Hi, I tried the new LED-RGB-CC-THRU and the copper pads are fused together. Is there a setting to fix this? I have Eagle 6-3.0.0
In the DRC dialog, change the “restring” value to a smaller size (0mil is OK). This value controls the smallest possible pad size and will override the pad size that the part was given in the library.
Mike, hey how’s it going these days!? So…I am getting into Eagle and just lost like a whole day due to this problem…learning how to make parts from scratch (it was worth it), thinking there was something wrong with the Sparkfun library. Now…I just stumbled upon your note here…trying to find where to set the restring value now…
(Update):…yeah, I’m still stuck. Don’t know what I’m doing. How do I do what you said to do?
Hey Gabe! Very sorry about that, restring is an annoying feature that I’d prefer we didn’t use, but it’s present on many of our designs. It’s a global override for pad sizes; even though the library may have a small pad, if restring is set to a larger value in your design, the pads will grow.
You can change it in your design in the board editor, in tools/DRC, in the restring tab. Play with the values for pads, if you make those values smaller (even 0), the pad size in the board editor should shrink as well. Hope you’re well, and hope this helps.
Thanks Mike! Great response time. So, setting all of the % values to 0 didn’t help, but setting my “Min” settings for “Pads” to 4 mil or less did do the trick! I also found this link here too (https://www.element14.com/community/community/experts/blog/2012/03/02/eagle–what-are-the-restring-settings-in-the-design-rules-for). I need to do some more reading. I’ll check the Eagle manual too. This is a bit confusing. Maybe you can add some info about restring into your Sparkfun Eagle tutorials? They have been super helpful thus far.
The SparkFun Library has now been updated as of 2/2/2013 for this through hole tricolor LED. You can find it under “LED-RGB-THRU” or “LED-RGB-CA-THRU” depending on the package under SparkFun-LED.lbr. If you are using the common cathode you can find it under “LED-RGB-CC-THRU.”

What resistors do I use with these when used with an arduino?
I’m a bit of a noob so this may be way off, but I believe it’d be 150 ohms for the red and 91 for the blue/green.
