Small form-factor GPS/GSM tracker
This entry was posted in data transfer and tagged GPS/GSM, tracker.
New version of small form-factor GPS/GSM tracker.
Change MCU to EFM32 increase standalone time (previous version use STM32 MCU)
Also change old BMA180 to MMA8562 and add 32Mbit (4MB) flash chip to save data if GSM not available or battery low.
Use MS Azure platform for web site and service for collect data from trackers.
Based now on GL865 but with Fibocom GSM dimensions reduce from 24×24 to 24×18 mm (GPS antenna size 15×15 on my hand)
