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.
If you have a standard USB flash drive attached to a USB host, Linux and LAN running the typical
consumption is around 0.20A.
When powered by the typical 3.7V battery the LAN and USB-hosts are disabled. The consumption
when Linux is running is around 0.75A.
The board can be powered either from the power jack or from the LIPO_BAT connector. Note that
since standard batteries can't provide the voltage needed for the board it is advisable to use the
power from the power jack. When you use the LIPO_BAT connector and a battery the chip
handling the Ethernet and the USB hosts is disabled. Also the power button has alternative function
when the board is powered by a battery – check 6.13.
If you have successfully powered the board the red 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.
