Subject of the issue
Powering my RPi3 + AutoPi DIY through an external 13.5 V supply (through the OBD connector) , my device keeps getting rebooted or turned off from time to time.
Steps to reproduce
I am currently trying to use the DIY AutoPi dongle to connect it to my own web service built on top Micosoft Azure using IoTHub. I need the device to always stay powered on, and am using an external power supply and powering my autopi through the OBD connector with 13.5 V. However, the device keeps rebooting randomly.
Is this expected? Is there a way to prevent this from happening? Can the power management feature be turned off?
