I bought Simcom SIM V_7.03 Gsm module, Can i get the datasheet for it, with external components too.
I am not able to understand purpose of additional circuit.
plz acknowledge me as soon as possible.....
Thanks for your post...but i had already went through many docs but I couldn't find proper explanation of Sim 300 Interfacing with additional components in detail.
Especially the purpose of inductors used and its values. Im very much confused....
