Welcome to a new InTheMail, the series that will touch both your passion for electronics and your bank account at the same time. We have a selection of different items received in this mailbag, I’m gonna start with this GPS module, the model number for this is ZX612 and it’s part of the Chinese gps trackers family, I think it uses a similar protocol to the relay gps tracker that I showed in a previous video and possibly connect to the same Chinese web server for data collection which poses the usual privacy risks but as I’ve shown in Voltlog #274, using a raspberry pi you can setup your own gps tracking server.
