1 - Power supply, power down resest, switched regulator, ground plane

All topics close to power suppies for GM862. In quick start guide and GM862 manuals is written, that you will get nearly 2 Ampere peaks after power on (AT+CPIN=XXXX) to the GM862, but power down reset is still a problem. Hopefully a few user will read this message and not do this "Frequently done mistake".
