Hi again Armadillo!
DDPAI mini X1 has direct 12V connection on it, so it does not need an external power adapter. This little power module I show is on the unit itself. It has a micro-usb input, but the micro usb cable brings 12V from car battery. Weird stuff. They clearly mention that you should not use that micro usb cable to charge your phone etc. I think they stopped selling this model because of these issues.
Anyway, good news, I tried your suggestion, connected PIN 1 to PIN 3 to enable the chip, and voila 3.3V output!
Now I checked the circuit board, and the enable signal is coming directly from the PIN 2 of micro usb 12V connector! But when I checked the original cable in the car, there is 0V on that pin. So it is not connected to the battery. Then it dawned on me, maybe it is a reserved pin for a special cable, and the 3.3V circuit could be just for that reserve function. Maybe there is a special cable that tells the camera that the ignition is off, and camera starts the special parking mode function, I don't know.
BUT! I put the camera together and you were right, it just works now! No problems with recording or connecting.
Now the question is, what diode should I put in the SD2 position? Looking at the sample circuit diagram above, I cannot see a need for it.
I am attaching an updated circuit diagram with values. It may be useful for someone else in the future.
Thanks for your help all the way, Armadillo.
