Cellular + GPS tracking, all in one, for your Arduino? Oh yes! Introducing Adafruit FONA 808 GSM + GPS Shield, an all-in-one cellular phone module with that lets you add location-tracking, voice, text, SMS and data to your project, in Arduino shield format for easy use.
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 (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
- Sensitivity
- Tracking: -165 dBm
- Cold starts : -147 dBm
- Time-To-First-Fix
- Cold starts: 30s (typ.)
- Hot starts: 1s (typ.)
- Warm starts: 28s (typ.)
- Accuracy: approx 2.5 meters
Sounds delicious, right? So we plated this fine module onto a shield with all the extras you need to make your next project shine.
- 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
On its own, this shield can't do anything. It requires a microcontroller like an Arduino to drive it! You will also need some required accessories to make FONA work. These are not included!
- 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!
- Each order comes with one tested and assembled FONA shield and a stick of 0.1" male header. Required Arduino, SIM card, battery, antenna and other accessories are not included! Some light soldering is required to put the headers onto the shield. You can also grab some stacking headers if you would like to stack a shield on top
There's also some recommended accessories. They are not required but chances are you'll want them!
- 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!
- SIM808 Hardware design
- SIM800 Command Manual - All the basic commands that the module supports (please note some are not supported by the FONA 808, such as FM radio, external audio, or bluetooth)
- SIM808 Specifications
- SIM808 GPS AT commands
- SIM800 TCP/IP App Note (specifics on TCP/IP GPRS)
- SIM800 FM Radio details
- SIM800 IP (FTP & HTTP) support specifics
- SIM800 E-mail support specifics
- SIM800 MMS (multimedia message) support specifics

below average value but decent quality on this 95.4% Polyester, 4.6% Spandex dress shirt
Special Size: Black Buttons, Size: Large, Color: Sky Blue, Special Size: Black Buttons, Size: Large, Color: Sky Blue
At $20 when I picked this up, it was overpriced for what it was. I'm held accountable to the value assigned to me at the time I select to review it, so I review the value based on what was assigned not on what it later becomes if they discount it. As I write this I can see it is in a value range it should have been for me, but I'm still reviewing it at the $20. That's overpriced on a 95.4% Polyester, 4.6% Spandex shirt (i.e., non-cotton) and so the value here is a 1/5 or 2/5, say 1.5/5 for it. In terms of quality, this is a poly dress shirt. Still, I'd call this a 4/5 for what it is.
The standard is cotton, and in my experience, as someone in ties and collared shirts all day, I would note that I do prefer a 95 cotton/5 spandex blend, with the challenge that its not the most wrinkle free material. This blend, 95 poly/5 spandex, is a very wrinkle free and smooth feeling material. Poly has better durability than cotton despite feeling thinner, because it won't fray as much. That said, even though it's lightweight, poly will make you hotter because it doesn't breathe like cotton. It feels light, so you think it is going to be cooler, but in practice actually isn't really if it's a hot day. It can make you sweat more.
That said, many people like poly blends for the ease of maintenance. I've given up dry cleaning, just too much, and I do like to avoid an iron, so I tested this out because of it. For me this fit well. I ordered a large (typically I prefer to wear a 16.5/34/35, and I'm 5'11, 185) and this fit well. It's not a slim fit (tapered bottom) for those who might complain about extra material. But it fit well. I put it through both the wash and dryer. It did not shrink (poly usually doesn't) to be out of size, but was fine, and of course came out without wrinkles. The collars have no stays, these poly shirts hardly ever do, but I have found they mostly remain flat, since the material doesn't tend to wrinkle, and thus my points stay in place just fine.
At a 1.5 on value and a 4 on quality, this is a 2.75/5 average for me. Again, value plays a big part for me. So, full disclosure a better value would have raised my rating on this. But hopefully, based on what I covered above, you have enough to figure out if this shirt is worth it to you or not.

Nice dress shirt
Special Size: Black Buttons, Size: Large, Color: Grey
This shirt is a super soft and an awesome style, which I really love. The material is a soft cotton and that doesn’t irritate my skin. It is breathable, but also keeps you relatively warm. It’s very nice looking on and would be okay for everyday wear. It has been used many times going out with jeans or shorts out. I wash and dry it regularly in a machine and still looks just as new as the out of box condition. There is no pilling, fabric change, or shrinking. The style is flattering, cut well, and runs true to size. Other shirts owned feel similar to this one, which meets expectations and is a nice shirt for the price. I do wish it had a pocket though. Ultimately would purchase again.

Sharp-looking business shirt at a great price
Special Size: Black Buttons, Size: X-Large, Color: Rhine Blue
This long sleeve dark blue shirt is a great choice for a business casual look. The "Rhine Blue" color really stands out — it’s very bold without being over the top, and it gives the shirt a sharp, polished appearance.
The stitching is very well done, with clean lines and no loose threads, which adds to the overall quality. It fits nicely and maintains a crisp look throughout the day.
The material is mostly polyester with some spandex, so it feels smooth, lightweight, and is actually breathable. It stays comfortable during long wear and doesn’t feel heavy or restrictive.
Overall, it’s a sharp, well-made shirt that delivers both style and comfort at a great level. It was a good deal at the original price of about $20, but at the new price of about $15, it's an excellent deal. I may get another in a different color.

Very comfortable and looks great!
Size: X-Large, Color: Navy Blue, Size: X-Large, Color: Navy Blue
This shirt is surprisingly really nice for the price. Really nice even regardless of the price. It fits and looks great on my hubby. We liked it so much that I bought him another one in a different color. Will probably even buy more. The large ran a little small, so we got him an extra large and it was great.
