Tutorial

Hardwares prepare:
1. Arduino Uno
2. GPS/GPRS/GSM Module V3.0
3. SIM Card
4. Earphone & Microphone
5. External power supply via the power jack
It is recommended you to supply 7~12v 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.
