Ring, Ring! Who's that callin'? It's your breadboard! Introducing Adafruit FONA MiniGSM, an adorable all-in-one cellular phone module that lets you add voice, text, SMS and data to your project in an adorable little package.
This module measures only 1.75"x1.25" but packs a surprising amount of technology into its 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. This version has a uFL connector. For the SMA version, click here!
- 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 little breakout 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 over the MicroUSB when necessary. Two LEDs let you know when its charging and done - 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 so you can run it with 2.8V to 5V logic. - Vibrational motor (buzzer) driver so you can have noiseless notifications - uFL connections for external antenna - Indicator LEDs for power and network connectivity - Standard SIM slides into the back
On its own, this module can't do anything. It requires a microcontroller to drive it! We suggest and use an Arduino but any 3-5V microcontroller with a UART can send and receive commands over the RX/TX pins.
