iMX233-OLinuXino-NANO user's manual
Notice that the pad numeration is written at the bottom of OLinuXino-NANO under the microSD
card connector. Please check the manual part for microSD card for a schematic of the pins.
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.
