What do these jumpers do?

I have a creality LD-002R and I was wondering what are the jumpers J5 and J7 for?
Would I be able to connect my RPi to communicate and control the printer with octoprint? I've added picture so you can see the labels for the pins.

If I understand it correctly you have to use USB and UART in order to connect the printer to your pi.

It looks like a Pi Zero 1/2 would be the best option for resin printers.

Thanks! Now that I have the info it makes thing a whole lot clearer.
