Arduino M95 GSM Shield

The Arduino M95 GSM Shield is helpful tool for those advanced hobbyists and

professionals, who want to get familiar with GSM data/voice comminication using their

Arduino board. Please read the M95 Hardware design and M95 AT Command Set

documentation first.

1. Hardware Requirements:

 valid SIM card - (not supplied)

 Arduino/Genuino UNO (ATMega 328P) or Mega (Atmega2560) - (not supplied)

 External power supply – (not supplied)

2. Technical requirements

 Operating voltage range: 6-12VDC

 Operating current: up to 2A DC during transmission bursts, make sure your power

supply is sufficient for powering GSM module during these bursts

3. GSM module:
