Hello.
I have a newbie question that makes me confused.

I have tried to search the forum and I have even try to google my question but with no conclusion.

What I wonder is how do you do a proper power connection
to the board?

There is one gnd (-) and one 12v (+) and one battery (+).
Do you need all three connected?
The supposed battery connection, is it 12v + from a battery? And the 12v + from a power supply?

Another question is about choosing good connectors for the power input and the sensors.
Any recommendations?

Hi,
With regards to connectors I have used pcb headers which are also keyed so you wont mix up the wiring, they also come in different pin configurations

Ebay item No 400344210802 are the type I have used

Ps
I have also used DuPont connectors which come in male, female and a mixture configuration in different lengths.

Note if you are going to use the wireless display werk recommends using connections as short as possible

Thank you for your answer.
Can someone tell me how to connect the power for the three connections?

If you are going to power from a 12v supply (wall wart or similar) tie battery and 12v + together and put on positive on the supply and negative to negative. See:

Thanks. That's what I thought but it was very unclear for me.
