In this section, you'll be introduced to:

  • The hardware of the DuoVero series.
  • Linux and our User Wiki.
  • Yocto - which is the "build environment" for writing code and developing an application using DuoVero products.

If you do not need an overview and just want to get started setting up your Gumstix system, then jump ahead to the "Getting started" section.

Introductory Videos

Gumstix has posted·a series of videos· that provides an introduction to the features and set up of several Overo and DuoVero configurations.


Hardware Introduction to the DuoVero series

The products in the Gumstix DuoVero series are divided into two areas:

  • The computer-on-module or "COMs", which are smaller than the size of your index finger.
  • The dual 70-pin expansion boards which provide the connectors needed for I/O functions such as USB, power input, LCD and HDMI and more. Each expansion board is the same size or bigger than the DuoVero COM so that there is room for the various connectors and I/O thru-holes and perhaps to fit around the LCD panel.·


Each Gumstix DuoVero COM can fit on every expansion board of the DuoVero series. Note that the Gumstix DuoVero series is NOT compatible with any products of the Gumstix Overo series.

Despite the small size, a Gumstix DuoVero COM and expansion board combination performs like a full-sized, Linux computer and can be programmed to perform a wide variety of functions in almost any application area including power management, time & attendance, security, access control, information technology, location tracking, medical, aviation, robotics and education, to name a few.


The main features of a DuoVero COM include:

  • Texas Instruments OMAP4430/4460 applications processor featuring the ARM® Cortex™-A9.
  • Package-on-Package (POP) memory: up to 1GB RAM
  • Bluetooth / 802.11b/g wireless communications module (optional)
  • microSD card slot.
  • Robust, 70-pin connectors on the lower side to bring out 140 signals from the OMAP4 processor
  • Four (4) mounting holes - one in each corner.
  • 17 mm x 58 mm.
  • 6 grams.

Product information for each DuoVero computer-on-module is posted on their respective product pages at www.gumstix.com, Make sure to review the information behind each tab of that product page for more technical information and product specifications.

Each DuoVero COM also brings a wide selection of signals to the two 70-pin connectors located on the bottom of the computer-on-module. The details of the assignment of signals and pin numbers for each of the two 70-pin connectors are posted in the Duovero System Reference

 A list of the expansion boards for the DuoVero series is available at www.gumstix.com.


Openly Published Schematics of Each Expansion Board

To assist customers in development of their a custom expansion board(s) compatible with and driven by a DuoVero COM, Gumstix makes the schematic of each expansion board available freely and without cost or licensing fees, via our website at pubs.gumstix.com.


Secure Mechanicals

Each DuoVero COM and expansion board configuration can·be secured together using either the white or the blue, plastic retaining spacers that Gumstix has made available in the accessories section of www.gumstix.com, linked here. Each DuoVero COM has a 0-80 mounting hole in each of the four corners of the Dvero COM for securing the COM to the expansion board.
