5.4 Powering up the device
The SBC-AVL needs to be connected to a power source (7 – 32 volt direct current). It can be powered
by a car battery, a rechargeable battery or a stabilized DC power supply. The USB connector is
available only for tracing and configuration functionalities; in case of the SBC-AVL Power, it can also
be used to charge the internal battery. If the SBC-AVL is connected only to the USB port, without VCC
and GND the GPS and GSM modules will remain switched off, even when the device is connected to
the USB port, it will not go into any kind of sleep mode. The SBC-AVL Power version else is able to
power up GPS and GSM modules also while just connected to the USB port, without main power.
