SIM800L GPRS GSM Module Core Board Quad-band TTL Serial Port with the antenna

This is the Small SIM800L GPRS GSM Module Micro SIM Card Core Board with a Quad-band TTL Serial Port and antenna. This module includes two antennas. The SIM800L GSM/GPRS module is a miniature GSM modem, which can be integrated into a wide range of IoT projects. You can use this module to accomplish almost anything a normal cell phone can: send SMS text messages, make or receive phone calls, connect to the internet through GPRS, TCP/IP, and more! To top it off, the module supports quad-band GSM/GPRS networks, meaning it works almost anywhere in the world. The first antenna is made of wire (which solders directly to the NET pin on the PCB) – very useful in narrow places. The second antenna is a PCB antenna with double-sided tape and an attached pigtail cable with an IPX connector. This one has better performance and allows you to put your module inside a metal case, as long as the antenna is outside.

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