IMX233-OLinuXino-MINI user's manual
control block. The processor's datasheet should be always the first piece of paper you consult when
dealing with electronics.
Notice that the pad numeration is written at the bottom of OLinuXino-MINI 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.

When removing the card, please make sure that you release it from the connector by pushing and
NOT by pulling the card directly (this can damage both the connector and the microSD card).
