Can i leave my gps plugged into the cigarette lighter?
When i turn my car off, the screen on my gps says charging even after i turn its power off. is this draining my car battery?? or do i need to unplug it every time i turn my car off?
does having my gps plugged in my car drain the battery while its off?
my car is a rsx-s 02. battery just died and had the gps plugged in overnight. there shouldnt be power going through the cigarette lighter plug thing right?
How to power a GPS module, microcontroller and a modem installed in a car ?
I can use the car battery ( 12 V ) to supply the power but how would I go about to getting that power to the 3 portable devices that’ll be installed in the car ? GPS module takes 12v, microcontroller takes 5V and modem takes 3V.
Need a voltage regulator of some sort but not sure how to go about it.. ANY suggestions would be of great help.
