code of the cable - GND=BLUE, RX(INPUT)=GREEN, TX(OUTPUT)=RED; note that RX of the
cable has to connect to TX of the board and vice versa.
Note that UART0 is multiplexed with the SD card.
6.2 SD/MMC slot
The microSD card slot is a standard 8pin connector.
The SD card can be used for booting the operating system for A13-OLinuXino-MICRO. It is
suggested to have an SD card with a proper Linux/Android image especially since you have ordered
a board from the A13 family without built-in memory.
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.
