OTEC - Object Tracking and Emergency Call Button Part-1

Child or elder person who has amnesia or demance should be kept under control. Parents wants to know where he (or she) is. On the other hand children may want to call parents.

This project is focused on this security. This device has a Quectel M95 GSM and Quectel L86 GPS modules. It has RP2040 mcu and w25q16 flash. Also have a lipo charger and sht30 humidity + temperature sensor.

This project will be open source by Hardware and schematics. Pcb will be ordered from PCBWAY.

Software will be minimal open source. I mean I will not share all of the functions that can run on this device. I will share only the functions that response back location info when you sent an SMS including location query.

I get pcbs few days ago. I mounted one and making tests on it. I will publish pcb order link (PCBWAY), schematics and component list when I saw there is no problem on pcb.

Now. Begin with the pcb photos.

Fr4 double Side pcb.

Mcu mounted and run led blink code.

Assembly of the second side.

I will share schematics, component and PCBWAY order link when I finish tests.

Here is the codes:
