Key Features
- Ultra-Compact Design: One of the smallest GPRS modules available, measuring just 16.8mm x 15.7mm, ideal for space-constrained embedded designs.
- Quad-Band GSM/GPRS: Supports 850/900/1800/1900 MHz bands for worldwide 2G network compatibility across all major carriers.
- Low Power Consumption: Approximately 3mA in sleep mode makes it highly suitable for battery-powered IoT deployments and remote monitoring systems.
- Open-Source CSDK: Comes with a comprehensive open-source C SDK, allowing developers to write custom firmware directly on the module without an external MCU.
- Rich Protocol Stack: Native support for TCP, UDP, HTTP, FTP, MQTT, and SSL enables direct cloud connectivity to platforms like AWS IoT, ThingsBoard, and custom servers.
- Multiple Interfaces: UART, SPI, I2C, and multiple GPIO pins provide flexible integration with sensors, displays, actuators, and microcontrollers.
- Voice & SMS Capable: Built-in voice call functionality with microphone/speaker interface plus full SMS support in both text and PDU modes.
- GPS Ready (A9G): The A9G variant integrates GPS positioning alongside GPRS, enabling location tracking without additional hardware.
- Industrial Temperature Range: Operates reliably from -30 degreesC to +80 degreesC, suitable for outdoor and industrial environments.
- Cost-Effective Solution: Delivers cellular connectivity at a fraction of the cost of 4G/LTE modules, perfect for applications where high bandwidth is not required.
