This is SIM808 Module GSM GPRS GPS Development Board. The SIM808 module is a versatile integrated module that combines GSM, GPRS, and GPS functionalities into a single board. Here are its key characteristics:
- GSM: Provides basic cellular communication functionalities, allowing the module to make and receive calls, send and receive SMS messages, and connect to the internet using GPRS for data transmission.
- GPRS: Enables the module to access the internet and send/receive data packets. It’s commonly used for IoT (Internet of Things) applications where low-bandwidth data transfer is sufficient.
- GPS: Incorporates a GPS receiver, allowing the module to receive location information from satellites, providing accurate positioning data.
- Integrated Development Board: Often comes as a development board that simplifies the integration of the SIM808 module into various projects. It typically includes necessary components, like power supply, connectors, and sometimes additional features for ease of use in prototyping.
- Serial Communication: Communicates with microcontrollers or computers using serial communication protocols (like UART), making it relatively easy to interface with various devices.
- Compact Size: Despite its multiple functionalities, it usually maintains a relatively small form factor, making it suitable for various portable or embedded applications.
- Applications: Widely used in tracking systems, vehicle monitoring, asset tracking, location-based services, and other projects that require cellular communication and GPS functionalities combined.
- External Antenna: Requires an external antenna for GSM, GPRS, and GPS functionalities to ensure proper signal reception and transmission.
When working with the SIM808 module, it’s essential to refer to the module’s datasheet and documentation provided by the manufacturer for detailed technical specifications, pinout information, communication protocols, and integration guidelines to effectively utilize its functionalities in your specific project or application.
Note: Refer to datasheet in the ATTACHMENTS section for more info. regd. the product.
