First off, great idea by Krisas Man for the flipped design. Full credit to him. Secondly, thanks No WaterMark for the ribbon cable path.
I did some adjustments:
- Re-aligned the mounting holes with the actual Pi Zero 2 W dimensions
- Changed the Pi Zero 2 W cover a little bit to fit another heatsink for wifi chip. It gets as hot as the CPU, and putting the heatsink helps reduce the temp by 2-3 degrees more. Also opening for the micro USB because i'm planning to use it with my Pi HD camera later. Find more info here: https://www.jeffgeerling.com/blog/2020/raspberry-pi-makes-great-usb-webcam-100
