The UART A6 GSM & GPRS Module from DFRobot is wireless module designed tooffera new way to enjoy outdoor IoT, and utilises the GSM protocol tooffereffective, ultra-low power communications over long distances withoutrelyingon a local WiFi hotspot. It is inspired by the global bike-sharingmovementand caters to objects, tools and devices that need IoT accessibilitybut maynot stay in the same place or have access to WiFi for extended periodsoftime. The module can be used as a simple node to communicate between systemsindifferent locations, or can be used as a phone thanks to the onboard3.5mmheadphone jack. This enables an endless amount of possibilities forthismodule, and with an integrated 1500µF electrolytic capacitor it is capableofworking well in a wide range of different situations and conditions. So,ifyou’ve always dreamed of taking your Internet of Things projects out intothebig wide world, away from WiFi and other local wireless transmitters,theDFRobot Original UART A6 GSM & GPRS Module is the perfect choice. _ Please Note: In the original DFRobot Tutorial, it's stated thatthedefault serial baud rate is set to 9600. This is wrong, and the actualdefaultserial baud rate is 115200._ UART A6 GSM & GPRS Module - Technical Specifications:| – 5V DC | – <3mA | – 2.8V (Arduino & Raspberry Pi Compatible) | – UART (TTL) – Onboard 3.5mm Headphone Port | – -30° to + 80°C | – 115200 | – 850/900/1800/1900MHz | – ≤105dBm | – 10 | – Standard SIM Only (Not Mini or Micro) - Communication Methods Supported
| – VoLTE – SMS – GPRS Data (85.6Kbps Down / 42.8Kbps Up) – AT Commands – Digital Audio & Analog Audio – HR, FR, EFR, AMR Voice Coding | – 34g | – 45 x 37mm Typical Applications for the UART A6 GSM & GPRS Module:Whilst this module offers a range of functionality that can be used forallkinds of different wireless communications applications, it hasbeenspecifically designed to act as a GSM-based IoT device, and as such manyofthe features complement this expected use case. This was inspired by thebike-sharing movement that has been growing in popularity throughout theworld,with the primary goal of this module being that it can constantlystayconnected to the network so long as it stays within signal-range ofGSMtransmission towers.

(Please note that Default Baud Rate is not 9600 as mentioned in this tutorial, and the default serial baud rate is actually 115200.)
- This handy tool is called AT Command Tester - Standard, and it is awesome for helping this module connect with modem devices, with an easy to use interface and the option for automated testing via scripts.
