Siemens TC35 GSM Module – SMS Text Message Voice Call Data PIC ARM Pi Arduino UK
The Siemens TC35 GSM module is a simple self-contained module that you can attach to a microcontroller or PC over RS232 serial for an easy way to send or receive text messages, mobile data or voice calls!
Simply attach a 5V DC power supply (centre pin positive) to the power supply connector, and a standard RS232 serial cable to the serial port. You can then send AT commands using any serial software – allowing you to make calls, send messages or use mobile data.
The module runs using a 3.3V regulator that is on board and a large number of header pins are provided – with useful signals allowing you to easily interface with the module.
A 3.3V TTL serial connection is provided on the port labelled JB3. This allows you to easily use the module with a microcontroller as part of an embedded system
For more information on the module, including details of the various headers provided on the board, please see the following documents:
