Схема: 32u4 with A7 GPRS GSM GPS v1.0

The new 32U4 with A7 GSM/GPRS/GPS Board is based on mega32U4 and A7 GSM/GPRS/GPS module. Compare to 32u4 with A6 GPRS GSM Board, it adds a GPS function,it also can call and send text message even via GPRS to upload data to server. At the same time it leads to an analog interface, an IIC interface and 2 digital interface. which you can connect to other module more easily.
Remote control and data acquisition will be more convenient.It is worth mentioning that this module can be powered by battery, and comes with a battery charging circuit, some IOT projects will make it take a leading role.
Add three GPS commands as follows:
AT+GPS=1 :OPEN GPS function
AT+GPSRD=1 : Get GPS information
AT+GPS=0: Close GPS function

GPS/GPRS/GSM Module V2.0 (DFRobot)

Опубликовано автор admin

This is a GPS/GPRS/GSM shield from DFRobot. This shield with a Quad-band GSM/GPRS engine works on frequencies EGSM 900MHz/DCS 1800MHz and GSM850 MHz/PCS 1900MHz. It also supports GPS technology for satellite navigation. It’s possible for your robot and control system to send messages and use the GSM network.
It is controlled via AT commands(GSM07.07 ,07.05 and SIMCOM enhanced AT Commands). And the design of this shield allows you to drive the GSM & GPS function directly with the computer and the Arduino Board. It includes a high-gain SMD antenna for GPS & GSM.
This GPS/GPRS/GSM shield uses an embedded SIM548C chip from SIMCom.Featuring an industry-standard interface and GPS function, the combination of both technologies allows goods, vehicles and people to be tracked seamlessly at any location and anytime with signal coverage.
