I wouldn't call it a copy, more like a derived work. As I say in the introduction, its a bigger brother to R-Kade Zero. The prototype uses the same PCB from R-Kade Zero but the plan is to design a brand new bigger PCB with controls, RPi Zero, LCD module and battery circuit.
I look forward to seeing how this develops; once it has the battery circuit this thing is going to be so versatile.
Is the screen connected via i2c mate? And are you planning on making the battery circuit modular too? It would be great - it can be swapped for bigger, better battery parts when necessary or even removed completely when not being used with the screen and being used with a TV.
This is basically a copy of your other project: https://hackaday.io/project/9844-r-kade-zero... why not continue it there?
