I would like to buy the small e-paper Shield. I need to connect it to Arduino Uno. I’ve read the spec and I know I have to use the SD card slot to make it works. I would like to know the specs of the SD card (max size) and in particular if I can use it as a datalogging memory (write info from other sensors) as well as a temporary data storage for the e-paper.
Thank you very much for the attention
