SM-5100B GSM/GPRS Module with Arduino (with Power connection))

I will just Mention Some Photograph which will give you clear instruction. There is a good tutorial Tronixstuff . Be careful about power supply connection. I should recommend use external regulated 5V power supply. 5V have to apply SM-5100B Vin pin and +5V pin. GND must be common. If you have any query you can find me on Facebook www.fb.com/NabilPhysics or call me +8801717973140.
