SIM800L V2.0 5V Wireless GSM GPRS MODULE Quad-Band MOD31 The SIM800L V2.0 (MOD31) is a member of SIMCom’s SIM800 series GSM engines and is presented in the AT-command manual as a compact cellular engine that exposes a standard AT command interface for controlling voice, SMS and packet data services. The manual frames the SIM800 family as a modem-style GSM/GPRS engine that is controlled by a host via serial AT commands, intended to be embedded into customer equipment rather than used as a finished product. The manual emphasizes the module’s command-driven design: it supports the standard 3GPP AT command sets plus SIMCom proprietary extensions so that a host microcontroller or PC can manage network registration, calls, messaging and GPRS data sessions via textual AT sequences. The document describes command categories for voice/SMS/GPRS/TCP-IP/HTTP/FTP/MMS and many service functions, showing that the SIM800L is designed to be operated and scripted entirely through these well-documented commands. Engineering detail in the manual highlights per-variant differences (the SIM800L is one of several SIM800 family variants), noting specific supported commands and hardware signals (for example jamming-detection pin and ADC support differences). The manual positions the SIM800L as a flexible embedded communications engine whose behaviour and services are exposed at the AT level making it suitable wherever a compact, commendable GSM/GPRS engine is needed in a larger device. Features: Standard AT-command control (3GPP TS 27.007 / 27.005 + SIMCom extensions). Support for voice calls and SMS control via AT commands. GPRS / packet data and TCP/IP commands (including TCP/UDP, multi-IP, PPP). HTTP and FTP client AT command support. MMS and email command support exposed in the AT set. TTS (text-to-speech) and local recording/playback command support. GPIO, ADC and audio channel control via AT commands (including CHFA, SGPIO, CMIC). Jamming-detection signal support (module PIN designated for JD status). Pin Description: 5v: Power interface Power the module CONNECT TO DC 5v GND: Connect to GND.
