SIM 800 L GPRS GSM Module with Wire Antenna

This is Small SIM800L GPRS GSM Module Micro SIM Card Core Board Quad-band TTL Serial Port with the antenna, in this module two antennas have been included.

SIM800L GSM/GPRS module is a miniature GSM modem, which can be integrated into a great number of IoT projects. You can use this module to accomplish almost anything a normal cell phone can; SMS text messages, make or receive phone calls, connecting to the internet through GPRS, TCP/IP, and more! To top it off, the module supports quad-band GSM/GPRS network, meaning it works pretty much anywhere in the world

First is made of wire (which solders directly to NET pin on PCB) – very useful in narrow places. Second – PCB antenna – with double-sided tape and attached pigtail cable with IPX connector. This one has better performance and allows to put your module inside a metal case – as long the antenna is outside.

Caution: Use a resistor divider circuit before interfacing it with Arduino to avoid the damage to the module.

Features :

1. TTL serial port for serial port, you can link directly to the microcontroller.
2. Don’t need MAX232.
3. Power module automatically boots, homing network.
4. Onboard signal lights all the way.
5. It flashes slowly when there is a signal, it flashes quickly when there is no signal.
