SIM800L GPRS - Original Chip

The development board equipped with the SIM800L module allows the use of GSM communication and GPRS features with development boards such as Arduino and Raspberry Pi. By using this board, you can send and receive SMS, track location, and even make your own cell phone. The SIM800L module on the board is responsible for GSM communication and GPRS receiver functions. The SIM800L is a miniature cellular module that provides GPRS transmission, sending and receiving SMS, and making and receiving voice calls. Its low cost, low footprint, and support for four-band frequencies make it a perfect solution for any project requiring long-range connections. After power is supplied, the cellular network is searched and the session is automatically opened. An internal LED connection status is shown (quick flashing: no network coverage, slow flashing: session opened).

SIM800L GPRS Module Technical Specifications:

Supply voltage: 3.8V - 4.2V

  • Recommended supply voltage: 4V
  • Power consumption:
  • Sleep mode <2.0mA
  • Idle mode <7.0mA
  • GSM transmission (average): 350 mA
  • GSM transmit (peek): 2000mA
  • Module size: 25 x 23 mm
  • Interface: UART (max. 2.8V) and AT commands
  • SIM card socket: microSIM (bottom side)
  • Supported frequencies: Quad Band (850/950/1800/1900 MHz)
  • Antenna connection: IPX
  • Status signal: LED
  • Operating temperature range: -40 to +85 °C
  • ATE0
  • AT+IPR=9600
  • ATE0&W
  • Code to be given for all baud rate Operation
  • AT+IPR=0

Right Pins:

  • NET - antenna
  • VCC : power voltage
  • RESET : reset
  • RXD : serial communication
  • TXD : serial communication
  • GND - ground

Left Pins:

  • RING
  • DTR : sleep mode
  • MICP, MICN : microphone (P + / N -)
  • SPKP, SPKN : Speaker (P + / N -)

Important Note 1: If communication with the SIM module is not established using the AT commands and a question mark is received as a response, you can perform these operations in Arduino by changing the result of the operation to 115200 baud rate and resetting the SIM800 module to 9600.

Important Note 2: The SIM800 module draws a high amount of current when connecting with base stations, so the power supply plays a crucial role. If you power the module directly with Arduino, it will mostly not work or be unable to connect with the base station. Therefore, it should be powered with a constant current using voltage regulators like LM2596. The module requires 3.7 to 4.2 mAh current, and it's crucial that this current be stable. If the SIM card you are using cannot communicate with the GSM operator, the problem is likely to be the power supply. Also, the PIN code of the SIM card you are using must be turned off.
