Bad LED on Charlieplex LED Featherwing

by dpy on Sat Oct 05, 2019 3:35 pm

Hi, I have a 15x7 CharliePlex LED Matrix Display FeatherWing with one LED near the center that is dimmer than the rest, or flickers. Is this something that can be repaired or replaced?

I have the feather wing connected to a basic proto 32u4, and the defect shows up both when powered from USB or from a Lipo.

Here's a picture taken while running the swirldemo.

The LED is dim no matter how many other LEDs are turned on at the same time.
