Very dim FeatherWing 128x64 OLED

Post by AdamSaenz »

Just getting around to trying out STM32F405 feather with the 128x64 OLED FeatherWing. I thought the display was not working, but it wasn't until some late night debugging that I noticed the very dim output of the display. Is there a output intensity adjustment or is this display defective? Including some pictures for reference; note they were taken with a 3 second exposure so they are actually much dimmer in real life.

OK, it should be nice & bright. Please email [email protected] with a link to this thread, your order number, and request the replacement of one 128x64 OLED Add-on For Feather - STEMMA QT.

Yes, I've used these and they are MUCH brighter than the example in the photo.
