Details

  • Brand: vige
  • Color: Blue
  • Manufacturer: vige

Features

  • This module is designed with 5v/3.3v single-chip logic conversion circuit, because the GSM/GPRS core is 2.8v, which is different from the logic level of ordinary single-chip 3.3v or 5v.
  • In order to have a stable control system, logic level conversion is indispensable.
  • The V_TTL pin is not used to power the GSM module, just to let the GSM module know that the TTL level it wants to output is ultimately converted to 3.3v or 5v.

Description

Features:
This module is designed with 5v/3.3v single-chip logic conversion circuit, because the GSM/GPRS core is 2.8v, which is different from the logic level of ordinary single-chip 3.3v or 5v. 
In order to have a stable control system, logic level conversion is indispensable.
The V_TTL pin is not used to power the GSM module, just to let the GSM module know that the TTL level it wants to output is ultimately converted to 3.3v or 5v.
