Sim800L GSM / GPRS Module with Micro Sim Card with Helical Antenna (PTA Non-approved)

SIM800L GSM/GPRS Module with Micro SIM Card and Helical Antenna (Non-PTA) is a compact cellular module designed for sending and receiving SMS, making voice calls, and GPRS data transmission. Its small size, low cost, and quad-band frequency support make it an ideal solution for long-range connectivity projects.

The SIM800L module is perfect for IoT, Arduino, and Raspberry Pi projects that require cellular communication. It automatically boots, searches for a cellular network, and connects without extra configuration. Its onboard LED indicates the network status: fast blinking for no coverage and slow blinking when connected.

Key Features

• Low-cost, compact GSM/GPRS module
• Quad-band frequency support (850/900/1800/1900 MHz)
• Supports SMS, voice calls, and GPRS data
• Compatible with Arduino, Raspberry Pi, and microcontroller projects

Power Requirements

• Peak current consumption up to 2A
• UART voltage: maximum 2.8V (higher voltage can damage the module)

Antennas

• Wire antenna, soldered directly to NET pin
• PCB antenna with pigtail cable and IPX connector

Module Pinout
