Skywatcher EQ8-R modification integrated Raspberry Pi

May I introduce the modification of my Skywatcher EQ8-Rh with the following points:

- fully restorable original!
- integrate Raspberry Pi 4 8 GB with Stellarmate/Astroberry
- uitilize DockerPi power board for Raspberry Pi (10-15V input, cooling, remote control on/off/shutdown)
- use GPIO/HW PWM (2 ports) with LR784 Mosfet Modules
- integrate GPS (BN-180/220)
- provide fully powered, integrated 4 port USB hub
- internal wiring, power + network input only

I try to translate and publish the entire BOM + description here, it will take a while. You can read/ autotranslate the doc from here:
