>> MICROLINK GSM - TINY ARDUINO WITH INTEGRATED GSM
Would have been nice to have this little device few weeks ago :)
The MicroLink GSM is a tiny self-contained Arduino inspired board that can
do automation, alerts, cellular data, phone calls, SMS text messages, and
much more that is also FTDI compliant for USB plug & play. The project is
currently being promoted on
It combines an an Arduino compatible Atmel328 micro-controller with a SIM800H
quad band GSM module and provides on-board battery (3.7V Lithium Ion Polymer)
connector in a tiny package that is only 50x32mm in size (about a third of
the size of a credit card).
It hosts 13 GPIO pins (digital and analog) and connectors for a tiny speaker
An interesting offering is the default sketch loaded on the device that
provides the unique ability to interface with the device over SMS to obtain
information such as the battery level, alerts, listen to the microphone
or read or write to the various GPIO pins on the device.
The project claims the device is very low power - boasting a 6 µA
power rating in sleep mode.
For projects that may need to additional storage space there is also a
version that incorporates a 4Mb 104MHZ SPI FLASH chip that in addition
to providing more storage also allows for over-the-air wireless programming
- great for remote or concealed projects.
Unlike many kickstarter.com projects that offer dreams and inspirations -
the device is already built and in use and has been extensively tested
so the campaign is purely around discovery and promotion and as
such is a low-risk investment; I will order mine now!
