Arduino has now released a new board, supporting wireless connectivity using GSM network, widening the scope for IOT development for hobbyists and people who do not have much experience in the field of networking.
Evolution of Arduino has always been a miracle to all competitors around the world. The development and support of Arduino community have enabled enthusiasts to reach out and learn new technologies in a matter of minutes. Now arduino has brought up with a new boards that enables wireless communication for IOT devices without an external GSM module. Behold, the Arduino MKR GSM 1400.
The board is powered by SAMD21 Cortext MO, 32 bit ARM MCU with a flash memory of 256 KB and an SRAM of 32 KB. It have 8 Digital IO Pins, 7 Analog Input Pins, 1 Analog Output Pins and 12 PWM Pins with support for UART, SPI and I2C Communication protocols.
Input power of this board should be in between 5V and 12V for stable operation. An optional LiPo battery can be connected to this board which will be automatically switched when one supply is not available.
Note: One thing to keep in mind while playing with this board is, the circuit uses 3.3V unlike other boards which uses 5V. So providing a voltage greater than 3.3V to any input pin could damage the board. In order to use this board with a 5V sensor, proper level shifting circuits should be employed
