I have a basic understanding of electrical systems and want to verify my findings before I commit to buying the component or frying my hardware.
Currently the plan is to connect this to my vehicles power (Ground & 12v) along with the ignition wire on the left side of the DCDC Converter (per manual). The right side of the DCDC Converter will connect to the PI's GPIO pins (2 and 6). PSW from the DCDC Converter will connect to another GPIO pin (??) when a script on the PI detects is closed, will issue a halt command.
- Is what I have above correct?
- What pins should I use for the PSW from the DCDC Converter?
- Do I need to do anything with pin 1 (3.3v)? I see other posts talking about it but I'm unclear what it does, or if its needed.
