Developed on the basis of a System on a Chip technology, Greenboard counts with a platform that allows it to be oriented towards diverse areas of development, among them, telecommunications.

To integrate various components in one board, presenting the functionality of a traditional computer but with an integrating capacity that allows it to adapt to highly complex scenarios are some of the features of Greenboard, the multipurpose board developed by the Scientific and Technological Center (CCTVal) and the Electronics department of the Federico Santa Maria Technical University, with the aim of developing mobile networks.

Javier Marto, Fernando Fuenzalida, Felipe Veas and Roberto Farias, Electronics Civil Engineering students, designed this device that has as predecessor a Chiliboard, a microcomputer board oriented to answering diverse requirements of the current market and that given its features captured the interest of Green communications, a French company, and that after proposing a series of new applications, it resulted in the development of five prototypes.

This way, and as with its predecessor, Greenboard was developed on the basis of System on a Chip technology, and as its name suggests it gathers in only one integrated circuit, the different components of a computer, converting it in the first device of its kind designed by university students in our country.

It´s important to highlight that this new board counts with a traditional operative system (Linux), so when a keyboard, a mouse and a monitor are attached, it can be used as a conventional computer; or to build a tablet.

The board is designed using the ARM A9 platform, which are low consumption chips like the ones present in cellphones. The processor is a Freescale IMX6, 2 GB of RAM, 8 GB of NAND memory, HDMI and USB ports, a micro SD card for external storage and a switch PCle that expands to two mini PCle ports, amongst other characteristics.

This new board was designed in its entirety by students from the Electronics Department and approved by the French company; who later on requested some modifications that transformed it into a device orientated to telecommunications, so that some functionalities not original to the design had to be incorporated meanwhile others had to be taken out.

Basically, it is a small computer of low consumption and when produced in high quantities its cost is reduced. Although it is oriented to the development of ad-hoc mobile networks, it can be adapted to any other kind of scenario like, mining, education or medicine, among others; being able to also become an attractive alternative to provide low cost desktops.

Currently, hardware and software testing is being done to verify the correct functioning of the device, and the tests to which the board has been subjected to-via simulation-, show that it meets regulations and could eventually be approved. Also pre-certification testing will be carried out, especially to those related to electromagnetic compatibility, which are demanded by the European Community.
