A10S-OLinuXino-MICRO user's manual
Additionally, there are the WP and CP switches that are responsible, respectively, for sensing
whether the card is locked for reading and whether there is a card inserted.
Note that there is multiplexing on pins A11 and B12 of the A10s processor. The SD/MMC1 and the
UART1 share the same data pins. This means it is not correct to use the UART1 interface and the
SD/MMC1 interface at the same time.
6.3 PWR jack
The power jack used is the typical 2.5mm one used by Olimex in most of our products. You should
provide 5 volts and the required current may vary depending on the peripherals connected to the
board. The power supply you use should be capable of providing at least 500mA of current.
