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.
This SIM800L breakout board is ideal for projects that needs to save space. This board draws a maximum of 2 A with an input voltage of 3.7 V to 4.2 V. This means you must not connect its pins directly to a 5 V Arduino! It doesn't even run on 3.3 V.
The solution is either to use a regulator or just have the SIM800L draw from a Li-Po (cellphone) battery.
Antennas are essential for this kind of module especially if your project is indoors. Without an antenna, there would not be enough transmitting power for the SIM800L to perform GSM services such as calls and SMS.
