SIM800L V2 GSM / GPRS Development Board Module with Antenna

Introducing the SIM800L V2 5V Wireless GSM GPRS Module, a quad-band module equipped with an antenna and a power supply for 5V. This module is designed for seamless integration with your computer's debug USB to TTL serial port. It delivers an output current of 800mA and is compatible with both 3.3V and 5V micro-controllers, allowing for immediate connection with a single-chip computer post-purchase.

Antenna and Global Communication

The module features an IPX antenna, enabling flexible switching between the PCB glue stick antenna and suction cups. With SIM800L's quad-band communication, data can be accessed globally, making it an ideal choice for international trade and projects.

Compatibility and Features

The SIM800L V2.0 GSM/GPRS Module is a quad-band GSM/GPRS module that is compatible with Arduino. It offers both GSM features (voice call or SMS) and GPRS features. The module operates on a 5V voltage level, allowing for direct connection with Arduino or any other system operating at a 5V voltage level.Unlike many GPRS/GSM modules on the market that require an additional 5V regulator and level converter circuit, the SIM800L V2 GSM/GPRS module comes with a built-in regulator circuit and TTL level converter on the board.

Pin Description

The module comes with the following pin configuration:

• 5v: Power interface to power the module. Connect to DC 5V.
• GND: Connect to GND.
• VDD: TTL UART interface. This TTL UART serial interface can be directly connected to the MCU like 51MCU or ARM or MSP430. The VDD pin is used to match the voltage of the TTL.
• SIM_TXD: SIM module Transmitter.
• SIM_RXD: SIM module Receiver.
• GND: If this pin is unused, keep it open.
• RST: Reset the module. If this pin is unused, keep it open.

Key Features

The SIM800L V2 GSM/GPRS Module boasts the following features:

• Network support: Quad-Band 850/900/1800/1900 MHz – compatible with GSM networks worldwide.
• TTL serial interface compatible with 3.3V and 5V MCU.
• Compact size suitable for all kinds of sleeve belt type and embedded applications.
• Features a card slot for easy mobile phone card replacement.
• IPX interface allows for flexible antenna change. The default PCB antenna greatly reduces space usage.
• Gold-plated board for more stable performance.
• Neat wiring ensures more stable board operation.
• Added protection device to prevent high pressure and reduce board loss, making it ideal for projects and learning.
