GPS/GPRS/GSM Module V3.0 (SKU:TEL0051) Robot Wiki

Earphone & Microphone

External power supply via the power jack

NOTE: It is recommended you to supply 712V@1A power via the power jack. When using

the GSM mode, the module requires an external power. But the power consumption is not

high,just 200mA@7v, when calling.

How to drive the GSM Mode via USB port

1. If your module is enabled, the indicator stat LED will light up, this means that the module is

running correctly. The LED marked "NET" will be lit when network communication has

being established.

2. Send the AT commands to the module by using Coolterm (http://freeware.the

meiers.org/CoolTermWin.zip)(or use the Arduino serial monitor).

NOTE: If you want to program the Arduino, please disconnect the coolterm to release the

communication port.

GSM mode & GPS mode Selection

Except using UART selection jumper caps(old version) or switch(latest version), you could switch

GSM and GPS function with the IO pins also. The UART selection is located on the bottom right

near the PWR STAT and NET LEDs. Remove the jumper caps connected for hardware UART

selection(old version) or set the switch in middle position(latest version) in order to control the

GSM / GPS by software.

Enable GPS mode & disable GSM mode:

Enable GSM mode & disable GPS mode:

NOTE: You could control GPS through the GSM AT commands, without requiring to enable

both independently. This way you can let the GPS enabled while using GSM network. Thus not

triggering a GPS reset.
