A9G Pudding GPRS GSM+GPS BDS Development Board SMS Voice Wireless

Description

Description: GPRS GSM + GPS BDS A9G Development Board (Pudding Board)

The A9G Pudding Development Board is a compact, all-in-one module that integrates GSM/GPRS communication with GPS/BDS satellite positioning, making it ideal for IoT, tracking, and remote data transmission applications. It is built around the A9G chip from AI-Thinker, combining cellular communication (2G) and location tracking (GPS + BeiDou) in a single, low-power module.

This board supports SMS, voice call, HTTP, MQTT, and GPRS data transmission, making it perfect for remote sensing, GPS tracking, and mobile communication projects. It features onboard micro-USB, SIM card slot, antenna interfaces, and GPIO pins for direct use with microcontrollers like Arduino, STM32, and ESP32.

You can interact with the board using AT commands via the UART interface, and it can operate independently or with an external controller for smart data processing and wireless communication.
