Questions about Robo Tank

[Rob F]

I was thinking similar that larger cards are slower because more to search. I don't think there's a minimum size but smallest I've tried is 512mb. As for size not much is need, on controller less than 1mb and display uses 27mb currently. There's some different settings and images on the cards. All the logs are written to the display card so it will increase in size over time. I think I calculated something like 20 years of data would fit on 2gb card.
