EMS (Embedded Module Series) SD / MMC / FRAM is a module to facilitate the interface between the SD (Secure Digital) card or MMC (MultiMedia Card) with a microcontroller that works at a voltage of +5 VDC.
SD or MMC cards can be used as a non-volatile memory that is easily replaced so as to facilitate the expansion of larger memory capacity. This module is suitable for applications that require data storage media, for example: attendance systems, queuing systems, or other datalogging applications.
