The LPE-MMC-V6 is an SD interface by Padial that supports two SD cards each up to 2GB. It was sold without case.

The interface was sold €70 alone or €130 with its slot expander (LPE-3SLTEXP-V6).

Another version very similar of the LPE-MMC-V6 was available with 4MB RAM. It is in fact a Memory Mapper cartridge PCB that prolonged this LPE-MMC-V6 board. This version was sold €120
