Introduction :

SIM800L GSM/GPRS module is a 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 internet through GPRS, TCP/IP, and more.

The module supports quad-band GSM/GPRS network, meaning it works pretty much anywhere in the world.

The SIM800L GSM / GPRS board features compact size and low current consumption with power saving technique,

The current consumption is as low as 1mA in sleep mode. It communicates with microcontroller via UART port, supports command. It’s operating voltage is 3.7 ~ 4.2V, peak current is 1A.

Features :

• Chip: SIM800L.
• Voltage: 3.7-4.2V.
• Support networks: Global quad-band network.
• Module size: 2.5cm x 2.3cm.
• TTL serial port for serial port, you can link directly to the microcontroller. No need MAX232.
• Power module automatically boot, homing network.
• Onboard signal lights all the way. It flashes slowly when there is a signal, it flashes quickly when there is no signal.

Applications :

• GPRS network nodes
• Remote communications
• Satellite positioning
• Real-time car tracking systems
• Security
• Internet of things (IoT)
