Adafruit CYBERDECK HAT for Raspberry Pi 400
PRODUCT ID: 4863
I was trying to use this with the suggested hyperpixel4. The screen kept losing the image and just had the backlit light. I thought the issue was the lcd screen, but after removing the cyberdeck from the equation, my lcd screen works fine.

Re: Defective item
We've just found that the Cyberdeck Hat has a diode that seems to cause a conflict with the HyperPixel's CS pin. It seeems to be an edge case.
You can fix it by cutting this trace on the Cyberdeck between the component and the via:
You can't use that pin while the two devices are connected to the RasPi anyway.
