    25 MHz quartz crystal Q2 is found at pins 60 and 61 of the Ethernet controller – LAN9512-JZX. 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 –...
  • Page 20 OLIMEX© 2012 OLinuXino User's Manual If measuring the current consumption it should be around 0.06A before initializing all the peripherals. The consumption raises to 0.12A without LAN and USB hosts initialized and Linux running. The consumption goes up 0.15A with the Linux running when LAN and both USB hosts initialized.
  • Page 21 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 – if you open it (cut it) - it disables the U6 DC-DC converter and enables a built-in the iMX233 DC-DC.

    OLIMEX© 2012 OLinuXino User's Manual Note that the SJTAG interface comes without plastic header mounted. The HW_DIGCTL_CTRL_USE_SERIAL_JTAG bit in the digital control block selects whether the one-wire serial JTAG interface or the alternative six-wire parallel JTAG interface is used. There are other options in the digital control block which might interest you and our advice is to check the iMX233's datasheet released by Freescale.
