SIM800C GSM Module

The SIM800C GSM/GPRS module is a compact, powerful, and versatile communication module that allows microcontrollers and embedded systems to connect to the GSM mobile network for voice, SMS, and data communication. It is a quad-band module that supports GSM/GPRS at 850/900/1800/1900 MHz, making it compatible with networks worldwide.

Key Features:

• Quad-band GSM/GPRS: 850/900/1800/1900 MHz

• GPRS multi-slot class 12

• GPRS mobile station class B

• Control via AT commands (3GPP TS 27.007, 27.005, and SIMCom enhanced AT commands)

• Supply Voltage: 3.4V to 4.4V (typical 4V)

• Operating Temperature: -40°C to +85°C

• Small size: 17.6 x 15.7 x 2.3 mm

• Low power consumption in sleep mode

• Integrated TCP/IP stack

• Bluetooth 3.0 (optional, depending on firmware)

• Embedded Internet service protocols: TCP, UDP, HTTP, FTP

• Supports SMS (text, PDU, and storage modes)

• Supports voice calls, DTMF, and echo cancellation

• Serial Communication (UART): Baud rate up to 115200 bps

Applications:

• Remote monitoring and control systems

• SMS-based alert systems

• GPS tracking (in combination with GPS module)

• IoT and M2M applications

• Smart meters and industrial automation

• Vehicle security and fleet management

Pin Configuration (common breakout board):

• VCC – Power input (typically 4V)

• GND – Ground

• TXD – Transmit pin (to microcontroller RX)

• RXD – Receive pin (to microcontroller TX)

• RST – Reset pin (active low)

• NET – Network status indicator (flashes LED)

• MIC+/MIC- – Microphone input

• SPK+/SPK- – Speaker output

• Antenna – External antenna connection (usually via u.FL or SMA)

Advantages:

• Compact form factor ideal for space-constrained applications

• Easy integration with Arduino, ESP32, Raspberry Pi, STM32, and other microcontrollers

• Robust GSM connectivity with global compatibility

• Versatile communication capabilities: voice, SMS, and internet
