SIM808 Module GPRS SMS Development Board IPX SMA with GSM GPS Antenna
A part of the review has been auto-translated.
Good module with SMA connectors on board. I tried to connect with USB/Serial module with success. I select 3.3V on USB/Serial module and connect 3.3V to VMCU on SIM808 board (you can see pictures). To get response you must first send character 'A' or 'a' and after module response on that you can send AT command (see picture).
These are very simple to use, for the most part, the commands in the documentation indicate AT+SGPIO actually is AT+CGPIO but PWM is AT+SGPWM???? the GPRS, GPS, Calls and Text are using simple AT messages switched on or off via the URC of the device (AT+CGNSINF= Get the GPS Position, AT+CGNSURC=5 set the output of the GPS every 5 seconds.....). However the Bluetooth is not enabled and seems to be un initialised in this firmware, Banggood Do You Have a Solution?

Very good value for money with all the antennas included. A very nice little board to learn how the sim 800 works
