Adafruit FONA - uFL Version Starter Pack

The Adafruit FONA uFL Starter Pack bundles the FONA Mini Cellular GSM Breakout (uFL version) with all the accessories you need to get started with voice, text, SMS, and data over 2G networks. The uFL version uses a slim sticker-type antenna for a compact, low-profile installation.

Built around the SIM800 quad-band GSM module (850/900/1800/1900 MHz), the FONA works on any global 2G network. The breakout board includes LiPo battery charging, level shifting (2.8–5 V logic), a TRRS headphone jack, vibration motor driver, and FM radio reception. It requires a microcontroller with UART (such as an Arduino) to drive it via AT commands.
