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.
