The latest Raspberry Pi comes with 2, 4 or 8 GB. I plan to get the 4 for an unrelated project, but will install PHD2 on it and guide my Meade LX85 with it to improve my software skills. Am plowing thought the excellent PHD2 documentation on Linux, but can't find memory requirements. I see some are using the 8 GB device. Is this a requirement? I would prefer the 4 GB. Any clues greatly appreciated.
I guess I should add, to make it a good project, I would probably use the Raspberry Pi to guide and image. Does that push the memory requirement up?
