TE0747 is a MicroSD Card sized (over-sized in length) Programmable Platform capable to be used as Google Project Vault device or as generic SD Card Emulation Device. TE0747 can also be used with custom Protocols or switched device that can be accessed as SD Card first to transfer files to on-board NAND, then later the microSD card edge terminals can be used as user I/O for other purposes.
