eMMC Adapter 
Adapts Hardkernel eMMC modules to a standard microSD card connector.
This allows eMMC modules to be read from and written to by using a standard microSD card slot on another computer. It also allows an eMMC to be used in devices that only accept microSD cards, although the combined size of the adapter plus the eMMC is considerably larger than a standard microSD card.
Please note: Not all microSD readers are compatible with the eMMC adapter modules and may result in non-bootable images. The USB adapter pictured below has been tested as 100% compatible.
The microSD reader pictured below is available for easy purchase from the "Included USB Adapter" drop-down above and shows how the adapter is used to convert from eMMC to microSD to USB.
