32 x 32 RGB Matrix wrongly soldered resister

by ModernBarbarian on Fri Oct 16, 2020 3:17 pm

Hello, I received a replacement for what I thought was a defective 32x32 RGB Led Matrix. The part I received had almost the exact same flaw, but when I emailed Adafruit Support, I was told "Our QA team has confirmed this component does not affect functionality" (even though the previous matrix was replaced). Can someone help me understand how this broken connection does not affect the matrix? Thanks!

It would appear to be a bypass capacitor, which helps remove electrical noise from the power line. It's helpful, but not crucial. You can see them scattered around the board.
