  • Page 17: Power Supply Circuit

    OLinuXino User's Manual 5.3 Power supply circuit The power supply circuit of OLinuXino-MAXI 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 recommended is 1A by default (0.250mA if 3.3VIO_E is closed – read below).
  • Page 18 OLIMEX© 2012 OLinuXino User's Manual The jumper 5V_E (5V Enable) which is closed by default enables powering the board via the power supply circuit. The 3.3V_E (3.3V Enable) jumper when closed enables the 3.3V power line. Note the 3.3VIO_E jumper which by default is closed – it disables the U6 DC-DC converter and enables a built-in the iMX233 DC-DC.
