GSM GPRS A6 Module

A6 is a simple GPRS transparent transmission module. The program has mature standard GSM07.07, 07.05 AT command and Ai-Thinker extended command to quickly get started, shorten the development cycle and lower the usage threshold.It is the smallest quad-band GSM/GPRS module with dimensions of only 22.8 x 16.8 x 2.5 mm .With its ultra-small size, low power consumption and wide operating temperature range, the A6 is the ideal solution for M2M applications for automotive, industrial and PDA, personal tracking, power environment detection, wireless POS, smart metering and other M2M applications. Provide complete GSM / GPRS SMS, data transmission and voice services.

A6 adopts the semi-hole process, which can realize the rapid production of modules through standard SMT equipment, and provide customers with high-reliability connection mode, especially suitable for modern, large-scale, low-cost production methods. The company adopts ISO9001 international quality management system, and provides products with high quality, low price and excellent service from all aspects of R&D, sales,warehouse, production quality and after-sales.
