  • Hi, can I feed the gsm module with 3.3v? I was thinking in making a voltage divider from 5v to 4v, but I think it will not draw enough current… I just want the module to receive and send sms. Can anybody help me? Is there any voltage regulator for this or can I just use a 3.3v regulator?

No public wish lists :(
