Hi,
here the finish design for the Prototypes.
First I have ordered 3 pcs for testing. I hope they arrived ready in 2-3weeks and the I can check... ;-)
For the Powemanagement:
If Enable is on 12V the Pi starts. If 12V is switch off, the Pi gets an low signal on GPIO4 (Pin7) so that the pi can shut down over a script. After 15s a Timedelay schuts down the step down regulator. In shutdown mode the the regulator draws 20uA.
I have decide for this Case: https://www.chinaenclosure.com/products/...xes-E.html
