Ring, Ring! Who's that callin'? It's your Arduino! Introducing Adafruit FONA 800 Shield, an adorable all-in-one cellular phone shield that lets you add voice, text, SMS and data to your project in an easy to use pluggable shield.
This shield fits on top of any classic Arduino or compatible, and packs a surprising amount of technology into it's little frame. At the heart is a GSM cellular module (we use the latest SIM800) the size of a postage stamp. 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)
- Make and receive voice calls using a headset OR an external 8Ω speaker + electret microphone
- Send and receive SMS messages
- Send and receive GPRS data (TCP/IP, HTTP, etc.)
- Scan and receive FM radio broadcasts (yeah, we don't exactly know why this was included but it works really well)
- PWM/Buzzer vibrational motor control
- AT command interface with "auto baud" detection
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 8Ω 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 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 Antenna - This slim uFL 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.

Not that Jack Black!
Size: 4 Piece Set
I bought this set assuming it was the actor/musician Jack Black’s skincare line. I figured a bearded celebrity would know all about quality beard care products. But actually it is not even named after a real person, it’s just a brand name. In fact, Jack Black the celebrity said he tried Jack Black products and they gave him a rash! Not a big deal though. I haven’t had such a reaction. The products smell fine, not overbearing, and seem to be working well. Cons: not exactly economical since it’s very small tubes. The beard oil pump is easy to overdo— Press too hard on the pump and you’ll end up with too much oil on your hands. A little goes a long way.

Wash/lube is travel/mini size
Size: 4 Piece Set
Did not realize beard lube and wash are mini/travel size but that’s my fault for not checking.

Never have I felt my beard this soft after using this beard oil…
Size: 4 Piece Set
I’m usually not the dude to leave a review on a product, but the second I hop out of the shower and tried the beard wash and beard oil, I was shocked.
Out of all the other beard oils and beard wash products i’ve used, this has to be the best result so far.
For the price, It can be expensive, sure. But it’s the only one you need. I don’t think i’ll ever go on a search for beard oil or wash ever again. This product is great!

Great kit for beards!
Size: 4 Piece Set
I had struggled with an itchy face/beard forever. Just thought my face was dry so I used lotion but it did not resolve the itch. Did some research and saw this brand recommended by multiple sites. I decided to give it a try.
Since using these products, my face/beard no longer itches! Shaving (cleaning up my beard edges) with the shave cream seems to feel much smoother too. It feels as it softens the hairs which then requires less effort to shave off.
Follow this up with the good and lightly scented beard oil to leave a smooth feeling, no-itch beard.
Would definitely love bigger sized containers but I would definitely recommend these Jack Black beard products.
