GSM overlay in connection with the board from Arduino Uno.
The device requires good quality power supply. It is recommended to use external power supply min. 5 V / 1 A for USB power supply or 12 V / 500 mA for Vin power supply. Do not power the cover plate from the USB port of your computer. |
Connection with Arduino
The system acts as an overlay for Arduino, using the following leads:
