u-blox C027 - car cigar power / battery
In a project i'm starting i would like using the u-blox C027 (has eg GPS, 3G onboard). The purpose is, using it in a car. My question: Can i power the u-blox C027 (out of the box, without modifications) via a car cigar power adapter or by bateries / battery power supply?

the C027 evaluation board can be powered with any power source that has a stable 12V output and is capable to provide enough current needed by the device - current consumption depends on the module type and its configuration (Transmission activity etc..).
Using the 12V from your car battery can provide enough current. The problem is that as soon as you start your car the 12V from the battery becomes full of spikes due to the ignition coils. These could damage your C027 board, so I do not recommend you to connect it directly.
You need to "clean" or "stabilize" the 12V from the battery before connecting it to the C027 board. There are multiple possible solutions to solve this problem.
