I'm gonna use this board for the fingerprint recognition application and will use a available .dll library (about 116KB) for doing that. After building a small project using some functions from this library, I find its size exceed the maximum size of code storage of the main MCU in the board.
so, I want to ask that, what is SD Card in this board used for? and Can I use this board for my app? if can, give me the guidance. Thank you very much!
