MK124 bottom row of LED s

The bottom row is all lit up; with the left most LED being 2x brighter than all other LED’s on the board.
All the links I have found on this forum for the schematic are bad 404 not found.

Thanks for the link.
Ay ideal why the bottom row is let up?

Most likely an assembly error.
Sorry, this forum does not allow picture uploads
If you can provide LINKS (e.g. by using a free online picture base) to HI-RES and SHARP pics of your assembly (both solder- and component side)
then we can take a look and provide some feedback.

Congrats with your little baby girl!

Overall soldering looks OK, however some joint might need rework.
Also, make sure to look for damaged tracks/pads.
A fully lit bottom row is related to pin 6 of the µcontroller, you might want to check that path.
The picture don’t show if the leds are positioned correctly, I assume you have checked this.

The bottom left LED was backwards. My bad; strange how bright it was.
Thanks for the clue in though.
I’ll fix and post an update.

That was the issue, all working now thanks for the help! :slight_smile:

Happy to read that it works!
