A6 GSM GPRS Module for SMS, Voice & Data Communication

The A6 GSM GPRS Module for SMS, Voice & Data Communication is a compact and reliable GSM/GPRS module designed for seamless wireless communication in embedded and IoT applications. Measuring just 22.8 × 16.8 × 2.5 mm, it is one of the smallest quad-band GSM modules available, making it ideal for space-constrained designs.

The module supports SMS messaging, voice calls, and GPRS data transmission, enabling developers to build connected devices with ease. It features support for standard GSM 07.07, GSM 07.05 AT commands, along with Ai-Thinker extended AT commands, helping reduce development time and simplify integration with microcontrollers such as Arduino, ESP32, and STM32. Its low power consumption, wide operating temperature range, and semi-hole SMT package ensure reliable performance in high-volume manufacturing.

Whether you're building IoT devices, M2M systems, GPS tracking solutions, smart meters, wireless POS terminals, automotive electronics, or industrial monitoring systems, the A6 GSM GPRS module delivers dependable GSM connectivity for SMS, voice, and wireless data communication.
