GSM/GPS module is a compact, flexible and powerful solution allowing to add GPS functionality and/or Internet connectivity to your own device with minimum effort. The module is designed as one of a few interchangeable transport connectors for DefendLineII project but could be easily mated with any microprocessor based device via serial interface and couple of extra GPIOs (two serial interfaces are needed in case of simultaneous usage of GSM and GPS chips). Depending on the required functionality only those components should be soldered that shall be used to provide that functionality which simplifies assembling process, makes the module cheaper yet still potentially capable of more – you can just add extra components later if you really need.

Main unit features:

  • SIM900D GSM module, one of the affordable GMS modules currently on the market;
  • Embedded TCP/IP stack, AT commands for TCP client/server connections, HTTP and FTP clients;
  • High sensitive and low power 12 Channel Copernicus GPS receiver;
  • SMT connectors for GPS and GSM antennas;
  • GSM Module debug output connector;
  • Microphone connectivity;
  • SIM card holder;
  • LED for indication of GSM module states;
  • GSM header (1-st serial interface, DTR/CTS, PowerOn and State control lines);
  • GPS header (2-nd serial interface);
  • Optional Li-Ion battery charger connector;
  • Optional Li-Ion battery connector with temperature control;
  • Power supply: 12V input (converted to 3.7V by onboard stabilizer for GSM module), 3.3V for GPS module (either external or provided by internal circuit if soldered). Instead of input 12V 3.4V (minimum voltage level for GSM module) might be provided, no need in onboard stabilizer. Power options are set by onboard jumpers;
  • Open source code library and circuit diagram unlock literally unlimited potential of this module;
