FeatherWing OLED - 128x64 STEMMA QT

by Powderedonut on Wed May 12, 2021 1:25 pm

Hi I'm having an issue with the featherwing oled display that just came in. I soldered the headers on the featherwing and connected it on top of a Huzzah ESP32. I tried running the example code and it shows on the screen but it is really dim and there seems to be some variation in brightness across the words. The buttons and reset do function correctly so I'm not sure what the issue is. I also tried connecting a STEMMA QT humidity/temp sensor and that worked fine but was also really dim. I've tried multiple power cables but that didn't help. Based on the weird discoloration, I think the screen just might be bad.

Can you post as good a photo of the underside of the board? I'm curious about the condition off the display connection.

That's a perfect shot. Thanks. I don't see anything amiss, so I figure it's the display panel. Let's try a new one.

Please email support@adafruit.com with a link to this thread, your order number, and request the replacement of one FeatherWing OLED - 128x64 OLED Add-on For Feather - STEMMA QT / Qwiic.
