SIM800 GSM Modem Module TTL with Antenna

Designed, Developed and Manufactured in India using SIMCOM SIM800 GSM/GPRS module. It is low cost, small size solution for users that only require TTL output for interfacing their GSM to any microcontroller like 8051, AVR, PIC, Arduino or ARM etc. It requires regulated power supply of 4V DC, ideally from a Switching regulator like LM2576. It has a SMA Connector and antenna for better network connectivity. If you are planning to use a metal enclosure make sure to place the antenna outside the enclosure.It is ideal for usage in development of Remote Controlled devices, Remote Monitoring, Call,SMS, GPRS and DTMF functions.

  • Small size- 5cm*3.5cm

  • Best for interfacing with any microcontroller- 8051, AVR, PIC, ARM, Raspberry PI, Arduino etc. or with a computer (requires external TTL-USB or TTL-RS232 Converter)
    Most common AT Commands followed.

  • SIM800 - GSM/GPRS module Designed for global market, SIM800 is a quad-band GSM/GPRS module that works on frequencies GSM 850MHz, EGSM 900MHz, DCS 1800MHz and PCS 1900MHz.

  • SIM800 features GPRS multi-slot class 12/ class 10 (optional) and supports the GPRS coding schemes CS-1, CS-2, CS-3 and CS-4.

  • With a tiny configuration of 24*24*3mm, SIM800 can meet almost all the space requirements in users' applications, such as M2M, smart phone, PDA and other mobile devices.
