My GPS logger project is pretty much over at last. All working so well, and several customers happy!
Do buy them (here) but they are not live trackers - they are loggers.
I have had an annoying set of issues.
- power control FET for GPS/SD picked wrong, way too low power.
- not spotting I had inputs on non RTC GPIOs on the ESP32S3.
- not realising the STAT signal from the charger is only charging so stops when charged.
- having a cap on GPS so it could brownout the power when connected.
Even so, all sorted, and quickly, and the whole project sorted from start to finish in a couple of weeks.
I'd like to thank Neil for inspiring the whole project - his blog: RevK's privacy-friendly GPS logger.
