5.3 Power supply circuit
The power supply circuit of OLinuXino-NANO allows only 5V of power. The board requires a
power supply or a battery capable of providing at least 0.25A (@5V) of current.
The board typically consumes between 0.12A and 0.16A while booting the Linux image with the
prebuilt software and SD card equipped. When no other peripherals are connected the board (except
the SD card) the typical consumption is 0.12A. With one flash memory stick the consumption raises
to 0.16A.
The board can be powered either from LIPO_BAT connector or from the power pin holes of CON2.
The pins used for powering are pins 1 and 2 of the CON2 row (over the SJTAG pinholes and behind
the UEXT connector).
If you have successfully powered the board the green PWR LED will turn on. Note that it is
possible to have the PWR LED on even if there isn't enough power for proper operation of the
board and all the peripherals currently connected.
