GSM/GPRS Quad Band TTL Micro Sim Card Board- SIM 800L

SIM800L Module is a miniature cellular GSM/GPRS breakout board that allows GPRS transmission, sending and receiving messages and making and receiving calls. This module supports quad-band GSM/GPRS network, which is available for GPRS and SMS data remote transmission.
 

The board features a compact size and low current consumption. With the power-saving technique, the current consumption is as low as 1mA in sleep mode. It communicates with microcontroller via UART port, supports command including 3GPP TS 27.007, 27.005 and SIMCOM enhanced AT Commands. It also has a built-in level translation, so it can work with the microcontroller of higher voltage than 2.8V default. Besides, the board also supports the A-GPS technique which is called mobile positioning and gets position by the mobile network. These features help the device to make a tracker.
 

Having a small footprint, quad-band frequency support and low price make it perfect for any project that requires long-range connectivity. The device uses a serial communication method, so it communicates with almost every controller via the UART port. After connecting the power supply module boots up, searches for cellular network and login automatically.

5. Supports Real-Time Clock
6. Supply voltage range 3.4V ~ 4.4V
7. Supports A-GPS
8. Supports 3.0V to 5.0V logic level
9. Low power consumption, 1mA in sleep mode
10. Compact size 23mm x 35mm x 5.6mm
11. Micro SIM Card
12. Searches for network and login automatically
13. Can connect any global GSM network with 2G sim
14. Miniature size
15. AT command interface with auto baud detection
16. Lead-out buzzer and vibration motor control port
17. Scan and receive FM radio broadcast, send and receive SMS and call

Specification:

1. Supply voltage: 3.8V to 4.2V (4V recommended)
2. Power consumption:
   • Sleep mode: <2mA
   • Ideal mode: <7mA
3. GSM transmission (average): 350mA
4. GSM transmission (peak): 2000mA
5. Interface: UART (max 2.8V, serial interface)
6. Command support: 3G PP TS 27. 007, 27. 005 and SIMCOM enhanced AT commands
7. Sim Card slot: microSIM
8. Supported frequency: Quad-band (850/900/1800/1900MHz)
9. Temperature range: -40 to 85 Degree

Note:

1. Module consumes 2A (peak)
2. The maximum recommended voltage in UART is 2.8V. More than this will damage the module
3. If the power supply can not feed the required current well, the module will shut down. It will reset in the middle of the action.

LED Indication:
 

1. Fast blinking: no network coverage or searching
2. Slow blinking: logged in
3. Not blinking: check the power

Package Includes:

1. 1X SIM800L GPRS GSM Module
2. 1X Helical Antenna
