μSD Card Slot
3.2.2
NXP i.MX6 processors offer many different SDIO interfaces, that can be used independently one from the other to implement different mass storages media
(internal eMMC, internal SD Card, external SDI/O interface).
Of these interfaces, i.MX6 processor's SDI/O port #4 is carried to a standard μSD card slot, soldered on top side of the module.
Please be aware that the μSD card slot is a flip-top type: this means that, in order to insert / extract / change a μSD card, the
heatsink/heatspreader must not be mounted, otherwise it will be impossible to access/open the flip top slot.
