GPS Logger project

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.
