I'm very in love with tracking devices and the solutions they can reach like never lose your pet (I have a cat) maybe track people or cars and the importance of these devices becoming smaller every day.
my goal with this project is
Use a combination of components like Modems and GPS modules connected to a MCU to send an accurate location to other device.
The specs are the follows
USB port to charge, power and communicate to the MCU
status led indicator
Modem LTE Cat M1/Cat NB1/EGPRS
