MobileNode is a circular IoT board


This open source, Arduino-compatible GSM/GPRS and GPS/GLONASS device provides real-time data anywhere, about anything.


The MobileNode is an open source IoT board, which was named a semi-finalist in last year’s Hackaday Prize and is now live on Indiegogo. Measuring just seven centimeters in diameter, the circular device is equipped with an ATmega32U4 MCU at its core, a GPS/GLONASS module for tracking and a GSM/GPRS chip for data transmission.

Makers can easily attach a variety of sensors to the MobileNode, including air quality (CO, CO2, O2, etc.), temperature, humidity, fire and motion, as well as add lights, servo motors and other electronic circuits. This enables the Arduino-compatible board to monitor air pollution, reduce energy consumption, collect real-time data, and even control food production machinery. What’s more, there are four holes for M1.2 or M1.4 screws, making it possible to house the MobileNode inside a box or case.

Every MobileNode comes with an attached tag, which contains both a public and private key. As its creators Oscar Rojas and Camilo Rojas reveal, you can push data to the cloud with the private key, while accessing such information via the public key. Meanwhile, GPS coordinates are shown in a Google Map along with the board’s orientation data given by its e-compass.

Aside from all that, MobileNode features an electret microphone that lets users hear what is happening nearby, a Nano SIM card socket, TVS diodes and Bluetooth. It is also possible to connect an external antenna to the GPS module, since some applications call for the MobileNode to be used indoors.
