Datasheet

6.2 SD/MMC slot

The microSD card slot is a standard 8pin connector.

We have tested a number of microSD cards on the OLinuXino boards and all of them worked fine

regardless manufacturer or capacity. However, keep in mind that some of the lower quality

microSD cards might draw too much current from the slot which might cause power-state problems.

If you suspect the microSD card is causing problems please try using another one of better quality

for better results.
