I have built and tested the prototype device, below are the pictures and video.
Top Side – GPS and GSM modules
Bottom Side – Power Supply and Microcontroller
Bottom Side – Li Ion Battery
Side – Supply, USB, MMC, SIM Connectors
I’ll upgrade this device to use PIC32 or DSPic30F3011 microcontroller because PIC1846J50 is unable to provide more processing power, I wanted to add more features like camera for taking still pictures inside and outside vehicle, immobilizer, fuel sensing, tyre pressure sensing, etc. I am also unable to find an enclosure for this prototype device so before I built the next revision first I’ll search for enclosure and then design the PCBs accordingly.
