Topic: tiny arduino on-board LED (Read 963 times) previous topic - next topic


this may not be the correct forum. i am trying to find the TINY LED's that are on the arduino board. i don't know what they are called, and googling tiny LED's doesn't work.  any suggestions ?


Surface mount device (SMD) LED should help.

The way you have it in your schematic isn't the same as how you have it wired up!


You will want one that is the right package size if you are trying to replace one on a printed circuit board. You may be able to get away with a different color, Im not sure how much that will effect it, but different colors have slightly different voltages, and may need slightly different resistors.

I think the LEDs i've seen on my uno, and nano are 0805 parts, but im not sure, and if you plan on replacing one of those LEDs, then you want it to be the right size for that location on the board (or you end up making things harder than they need to be.)


0805 is about as small as most people can hand solder.

1206 can be done fairly comfortably. Most of those leds are signal leds.

PLCC(-4) and 5050 are very hand solder-able but they are primarily to provide illumination - can be used for signaling purposes. I prefer plcc myself and use them in place of 1206 leds for signal purposes.
