128x64 OLED Bonnet .. OLED dark

Post by davidmcq137 »

Hi Guys,

I just received an order that includes a part # 3192 OLED bonnett. I've installed the code example from the PDF on this product on a Pi-0. I've added print statements to the buttons.py demo to confirm that it's reading all the buttons correctly, but the OLED remains dark. I can only conclude that the display itself is not working though the card seems to be at least partly functioning .. at least the wires from the buttons to the GPIO pins. Happy to perform any diagnostics if that might help.

Sorry for the delay. I wanted to setup the hardware and run through the guide to make sure it still works as written:
https://learn.adafruit.com/adafruit-128 ... y-pi/usage
And it did.

Can you post a photo of the bonnet so we can see if there's anything obviously wrong. Also a photo showing the solder job on the Pi Zero headers.

Thanks. That soldering looks excellent. It must be something with the display. Let's replace it. Send an email to [email protected] with a link to this thread and your order number and they can get your a replacement. Looks like you originally got this as part of a kit, but you only need a replacement PID 3531.
