Getting Started-V1.0

Usage Notes

1. Compatibility

   This shield is compatible with Arduino board like Arduino UNO, Arduino Mega1280 and Arduino Mega2560 (5V standard operating voltage).
   Note: It needs external power supply (6-12V) for the higher power consumption as the GSM mode.

2. Status light

   PWR: Power indicator;
   NET: Net connect indicator:

   • 64ms On/3000ms Off - module are connected with net;

3. Enable module button

   Press the button for 2 seconds to boot/shut down module.
   Note: This button is connected to digital Pin 12, so you can also boot/shut down module by setting the Pin12 value.

4. USB/Arduino Switch
   None: Push to this side when uploading sketch to Arduino board like Uno, Mega except the leonardo.
   Arduino: communicate with Arduino through the sketch.
   USB: communication with PC through the serial(USB cable).

5. mic&speaker channel

   These socket and pin are used to play TTS and dialing.
