Hi,
I have remote car starter and it has a external trigger wire so when that wire is connected to car body (ground) it start/stop car, and I would like to make a PCB relay that will be connected to particle boron MCU.

There is no high amp load on that wire so its just for making connection (spark) to car body so I don’t want to put a big relay.
Is there anything i can use for making PCB with boron /esp32 etc.?

curranty I am using the following

Greetings,

The relay mentioned would seem suitable for switching a small logic signal.

If you are building your own board however, I would suggest that a small solid state relay such as the CPC1017NTR may be a better choice; it is easier to drive and does not have mechanical contacts that can possibly corrode.
