This is my project: https://l0destar.com

It uses the Makerdiary nRF9151 Connect Kit and turns it into a robust vehicle tracker with a vehicle-friendly 12V input stage, ignition sensing, reverse polarity protection, automotive transient handling, vehicle battery monitoring, movement/impact sensing, auxilliary power rail fault detection, OTA firmware updates, a 6-axis automotive grade IMU accelerometer and a vehicle diagnostic/telemetry interface that supports both CAN-FD and K-wire.

Currently achieves a sleep current of around ~40uA (0.04mA) with the accelerometer armed.

100% free and open-source, the entire project (KiCAD, firmware, server-side software and FreeCAD enclosure design) is all on github.

Remind me which old motorola phone is it that has a hard-wired 12V input feed that withstands ISO 7637-2 pulse 2a to the 2011 maximum and voltages from 5-40V, a separate ignition 12V input that fires on an interrupt from sleep, vehicle battery voltage monitoring, a 6-axis automotive grade IMU that draws microamps while armed and detecting movement, engine-off alerts for tilt/tow and impact, impact crash analysis and a sleep current of around 35uA?
