Powering directly with 12v would be nice, however both the relay module (https://www.espruino.com/Relays) and the ultrasonic sensor (https://www.espruino.com/HC-SR04) might have a problem I've guess...

I'm in the middle of a small 'car-project' and was wondering what is the best of powering the board in a car.
I was thinking about just using a 12v 'mobile USB' charger and plugging the board in.
Is there a better / more correct way?
EDIT - damn you autocorrect (title is wrong and I've can't change it). It's a Pico board!

Hi,
Thanks for all your replies- I have to give it a try to see how it works in real life.
After googling a bit I've found this: https://www.engadget.com/2007/03/13/how-to-make-a-solid-state-a-v-switcher/
I have no idea if that would prevent the flash/glitter, but within the next days I'm gonna test the switch... - and after that the IC from the link...
thanks 👍
Edit... just a small thought- it's the exact same camera the 2 sources. They are just pointing in 2 different directions - would that make any change in the synchronization?

I'm trying to create a small project where I have 2 composite video outputs and 1 monitor.
To switch between the 2 sources (no sound - only the yellow video cable), I was thinking using the relay module (https://www.espruino.com/Relays) and connect it as:
Output to monitor: K1 Pole
Output from source 1: IN1
Output from source 2: IN2Ground / shield from the 3 cables would all be connected.
Could I've use the relay module to handle the video signal or would the module generate to much noice?
That just gave me an idea...
Relay module in 12v would be nice.
Ultrasonic sensor... has anyone tried with a normal VW/Audi PDC sensor? They are running 12v (link to eBay for a random sensor: https://www.ebay.de/itm/122453670270)
3 pins:
1: 12v
2: signal (I don't know anything about that)
3: Ground
