A MicroSD card or an eMMC module is required to boot the OS. We recommend this eMMC module for faster OS booting, quicker application launching, seamless multi-tasking and efficient access to the cloud.
This 64GB eMMC Module has Android pre-installed to run out of the box .
To flash or update the OS of the eMMC Module you need an eMMC Module Reader.
