The Ai Thinker A6/A7/A6C Module User Manual provides specifications, pin descriptions, and AT command usage for GSM/GPRS and GPS/AGPS functions.
This manual covers the main specifications of the Ai Thinker A6, A7 and A6C modules, including dimensions, operating temperature, voltage ranges, supported GSM/GPRS bands, data rates, and certifications. It also details the hardware interfaces such as UART ports, GPIO levels, and camera connections.
Detailed pin‑out tables for each module version are provided, along with the AT commands needed to control power, low‑power mode, GPS/AGPS activation, and data transmission. The document includes notes on hardware design examples and references to the optional breakout boards. This manual is written in Chinese.

Apply more than 1.9 V to the PWR_KEY pin for at least 2 seconds.
Set GPIO1/INT low to enter low‑power mode; set it high to exit. In this mode standby current is below 1 mA.
Send AT+GPS=1 to turn GPS on and AT+GPS=0 to turn it off.
