I purchased the hardware from this guide, including the 2.8in waveshare display found in the parts list section.
The only thing i'm using different is i've swapped the pi zero for a pi zero 2w.
The screen briefly flashes I can see the underscore blink but then the screen goes blank. I can SSH into the device though.
