GA6-B mini GPRS / GSM module A6 SMS / voice data over wireless boards SIM800L
Hardware changes:
1. The previous version of Pwr required pull-up to boot, now it is pulled-down to boot.
2. The blue indicator was originally connected to TXD, but now it is connected to the network indicator NetLight pin.
3. The size is the same, the Mini board pin is compatible with the old GA6 V2.0
AT firmware changes:
The original transparent transmission setting instruction is canceled ---> AT + KCDATAMODE controls whether the connection to the server successfully enters the transparent transmission mode
Replaced by: AT + CIPMODE Controls whether the connection server successfully enters the transparent transmission mode
For other minor changes, please see GA6-B AT instruction set V3.03

---------------- GA6-B module advantages ----------
Wide area coverage: GPRS has good coverage in 34 provinces, and it is a popular 2G communication standard. Basically, where the mobile phone can make calls, you can access the Internet through GPRS wirelessly;
Always online: As long as the GPRS application is activated, it will remain online, similar to a wireless dedicated network service.
Pay-As-You-Go: Although the GPRS service is always online, you don't have to worry about the cost; you only charge when traffic is generated.
High-speed transmission: At present, GPRS can support a peak transmission rate of 85.6Kbps, and the theoretical peak transmission can reach more than 100 Kbps.
Inexpensive: Compared to SIM series modules, the price is only half of that. Greatly reduced
Entry threshold for IoT devices;
With its smaller size, lower power consumption, and wide operating temperature range, GA6 is the ideal solution for M2M applications, suitable for automotive, industrial and PDA, personal tracking, power environment detection, wireless POS, smart metering, and other M2M applications To provide
GSM / GPRS SMS, data transmission and voice services.
