NOTE:

1. Software/Hardware Serial Port Switch: Arduino UNO/Mega controllers connect USB with the

hardware interface D0,D1 in default. So serial port conflicts are common when serial ports are used

by the expansion shields. Considering these conflicts, SIM7000C Arduino NB-IoT/LTE/GPRS expansion

shield equipped with a software serial port to communicate with Arduino. Learn more about Arduino

SoftwareSerial Library.

2. Boot button connected to D12 in default to control program conveniently. You can pull up D12 for 2s

to ON/OFF. SIM7000C ON will initialize to get ready to work in about 2s.
