This shield fits right over your Arduino or compatible. At the heart is a powerful GSM cellular module (we use the latest SIM808) with integrated GPS. This module can do just about everything
- 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 (MT3337 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
- 22 tracking /66 acquisition channels
- GPS L1 C/A code
- Tracking: -165 dBm
- Cold starts : -148 dBm
- Cold starts: 32s (typ.)
- Hot starts: 1s (typ.)
- Warm starts: 5s (typ.)
- Accuracy: approx 2.5 meters
- Onboard LiPoly battery charging circuitry so you can take your project on the go. Use any 500mAh+ LiPoly or LiIon battery and recharge via the Arduino when necessary. Two LEDs let you know when its charging and done. You can then flip the switch and use the battery to run your circuit!
- Standard 4-pole TRRS headphone jack. Use any 'Android' or 'iPhone'-compatible headset with mic
- Breakouts for external 32Ω speaker and electret mic if you don't want to use a headphone
- Level shifting circuitry to make it Arduino-safe
- Vibrational motor (buzzer) driver so you can have noiseless notifications
- uFL connection for external passive GPS & external GSM antenna
- Indicator LEDs for power and network connectivity
- Any standard 2G SIM slides into a secure connector
- SIM Card! A 2G Mini SIM card is required to do anything on the cellular network. US AT&T no longer sells 2G SIMs and will shut off their 2G network, so for American customers we recommend any T-Mobile or reseller (TING, SIMPLE mobile, etc) that uses the T-Mobile network.
- Lipoly Battery - 500mAh or larger! This 500mAh battery, or this 1200mAh will work great.
- External GSM Antenna - This slim uFL antenna works great!
- External Passive GPS Antenna - This 15mm passive antenna works great!
- TRRS 4-Pole Headset - Any 'iPhone' or 'Android' compatible (but not iPhone original) should work. We tried about 10 different ones, and basically the more expensive once are more comfortable and louder but our official iPhone headset mic did not work.
- External Mic & Speaker - If you want to talk directly to your FONA, an electret mic and mini 8 ohm speaker will do quite nicely.
- Vibrating motor - the FONA can drive this directly, just solder a mini vibrating motor disc in!
