This is SIM800C Module SMS Data Replaces SIM900A Development Board Spring Antenna. The SIM800C is a GSM / GPRS Quad-Band with very compact dimensions and low power consumption. It can communicate with the MCU controller via AT commands and TCP/IP standards. Being perfectly manageable from MCU and development kits as Arduino, it is widely used to develop very compact devices such as trackers, GSM telephone combiners, remote control, remote alarms, etc.

Features:

1. Easy to use
2. Support voice calls, SMS, and GPRS at a speed of 85.6kbps in down and 42.8kbps in up.
3. It supports digital and analogue sound audio, HR, FR, EFR, AMR voice coding.
4. It supports two serial ports that can be connected directly to the MCU without the use of a MAX232.
5. Good quality product
