Hi, not sure where to ask. I want to add memory to an arduino. It would store data in the form of files of differing types. Drivers etc. Say 100 megs which could be interrogated/downloaded through a usb port. This would not need to be written by the arduino so could be removable or eprom etc, needs to be non-volatile though.
Eventually this would be a custom board so am looking for the best (cheapest) method. i.e. it might be better to solder a chip to save the cost of an sd card socket.
Any ideas please ? Initially it would be on a shield proto board though.
ideally it would be recognised as a drive when plugged into a PC.
