  • Page 21: Power Supply Circuit

    OLinuXino User's Manual 5.3 Power supply circuit The power supply circuit of OLinuXino-MINI allows flexible input supply from 6V to 16V direct current. This means a wide range of power supplies, adapters, converters are applicable. The maximum amperage the board can draw is 1A.
  • Page 22 OLIMEX© 2012 OLinuXino User's Manual Note that the whole 3.3V part is not mounted (elements marked as NA) by default because we use the internal 3.3V DC-DC convertor in the iMX233. However, the internal DC-DC in the processor is not very reliable when a lot of current is required. It is better to mount the elements of the 3.3V part circuit if you wish to use 3.3V at heavier loads.

    OLIMEX© 2012 OLinuXino User's Manual 6.8 Battery connector When using the battery connector keep in mind that it is an energy solution that wouldn't be able to power the board and all the peripherals. The voltage of a 3.7V LIPO battery would be enough to power the processor and the memory but probably won't be enough to power all the devices you mount on the USB hosts.

Note that the jumpers are SMD type and opening a jumper would require cutting, closing a jumper would require soldering. To be able to do the quoted operations you will need basic engineering skills and experience.

    2) 3.3V_E open (unsoldered/cut), 3.3VIO_E closed (soldered) In the default variant 1) the board uses the mounted by OLIMEX DC-DC 3.3V convertor which when the board is powered by external supply is the better alternative. However, if you use battery it will not power the chip handling the USB and the LAN functionality.
