2.3 Powering the board
The board is powered in one of the following ways: 1) by PWR jack, 2)by JTAG/SWD programmer
(3)by USB-OTG.
The PWR jack should be supplied from a 6V to 16V source with maximum current of 1A from the
power jack. Without additional components and peripherals (no microSD card mounted, nothing
connected to the USB, etc.) the typical consumption is 30mA @ 12V. For the European customers
we sell an affordable power supply adapter 12V/0.5A - SY0612E.
It is worth mentioning that the board can NOT be powered by the battery connector. The battery
connected keeps some of the processor's functions remain intact during power down but it provides
insufficient power for the board to operate properly. For example the RTC doesn't loose the values
when there is a battery connected.
2.4 Prebuilt software
Upon powering initially the board's red PWR LED and the green PWR LED should turn on.
