SIM808 GSM GPRS Module is at the heart of our Adafruit FONA 808 – Mini Cellular GSM + GPS Breakout. For people who want to integrate a cellular (GSM/GPRS) module into their design without the full breakout, this hand-solderable module is pretty nice! Please note we don’t provide any tech support for this module, but we do have a schematic as well as a collection of datasheets and app notes that can be used to interface.
Quad-band 850/900/1800/1900MHz – connect onto any global GSM network with any 2G SIM (in the USA, T-Mobile is suggested)
Fully-integrated GPS (MT3336 chipset with -165 dBm tracking sensitivity) that can be controlled and query over the same serial port
Make and receive voice calls using a headset or an external 32Ω speaker + electret microphone
Send and receive SMS messages
Send and receive GPRS data (TCP/IP, HTTP, etc.)
PWM/Buzzer vibrational motor control
AT command interface with "auto baud" detection
Here's the GPS specifications:
22 tracking /66 acquisition channels
GPS L1 C/A code
Tracking: -165 dBm
Cold starts : -147 dBm
Cold starts: 30s (typ.)
Hot starts: 1s (typ.)
Warm starts: 28s (typ.)
Accuracy: approx 2.5 meters
You’ll need to add all of the supporting circuitry that is required, such as antennas, power regulation, any level shifting, LEDs, etc!
