SIM800L GPRS GSM Module Core Board Quad-band TTL Serial Port

About this item

SIM800L GPRS GSM Module Core Board:

The SIM800L GPRS GSM Module is a compact, cost-effective solution for GSM and GPRS communication, powered by the reliable SIM800L chipset from Simcom. Supporting quad-band GSM, this module is ideal for global connectivity and a wide range of IoT applications. Despite its small size, it delivers robust functionality, including SMS, voice calls, and internet connectivity, making it perfect for space- and budget-conscious projects.

Capabilities:

• Send and receive SMS messages.
• Make and receive voice calls using a headset or external speaker and microphone.
• Access the internet via GPRS for TCP/IP and HTTP communications.
• Control vibration motors (buzzer) using onboard PWM functionality.
• Receive FM radio broadcasts for added versatility.

Power Considerations:
The SIM800L operates at a voltage range of 3.7V to 4.2V, requiring a dedicated power supply as it cannot be powered directly by platforms like Arduino or Raspberry Pi. It also demands up to 2A current, making a 3.7V LiPo battery or a suitable step-down power supply the preferred choice.

Communication:
The module supports UART communication with standard 3GPP TS 27.007, TS 27.005, and Simcom-enhanced AT commands for easy configuration and control.

Key Features:

• Quad-Band GSM: Operates on 850/900/1800/1900MHz, compatible with global 2G networks (e.g., T-Mobile in the USA).
• Voice Calls: Support for external 8Ω speaker and electret microphone or a headset.
• GPRS Connectivity: Enables data communication over TCP/IP and HTTP.
• PWM/Buzzer Control: Integrated driver for silent notifications using vibration motors.
• Antenna Options: Includes onboard IPEX socket for external antenna connection via uFL or SMA.
• Level Shifting: Compatible with logic levels from 2.8V to 5V.
• Indicator LEDs: Built-in LEDs for power and network status monitoring.
• SIM Slot: Standard SIM card slot conveniently located on the back.

Applications:
The SIM800L module is ideal for:

• IoT projects requiring SMS, call, or internet functionality.
• Building custom GSM-enabled devices like mobile phones or tracking systems.
• Integrating voice and GPRS capabilities into automation systems.

Compact, versatile, and packed with features, the SIM800L module is the perfect choice for embedding GSM and GPRS functionality into your next project.
