ODROID-XU4 USER MANUAL
eMMC Module
Align the eMMC module and the eMMC connector on the XU4
board, using the white rectangle on the PCB as a guide. The female
portion of the eMMC module should line up with the male connector
on the board. Slowly push it in until it clicks in place. Be gentle. If you
are unable to push it in, it may be misaligned. Recheck and turn the
eMMC module if you notice a wrong insertion direction. The writing on
the card will be exposed after insertion. The image below depicts how
the eMMC module appears after it is mounted.
