“Today’s DIY is tomorrow’s ‘Made in America,’” President Obama proclaimed in his opening remarks at the White House Maker Faire in June 2014. To commemorate the rise in DIY innovation, the White House sponsored its first-ever Maker Faire and invited makers of all ages from around the country to show off their innovations. Projects ranged from robotic giraffes to a mobile 3D printing fab lab.
Part 3: Does using a module let you save costs over the complete lifetime of the project?
1. Concept phase: Feasibility study, analysis of components, time and personnel requirements is approximately $70,000 for an i.MX6 based project. This can be reduced to $27,000 if using an embedded module.
2. Circuit diagram: Preparing a circuit diagram with an integrated processor and memory is going to cost $30,000. Using an embedded module reduces the complexity and can bring this cost down to $6,500.
3. Layout: Since the application board is simpler to put together with a modular design, $13,500 to $15,000 will usually suffice. With an integrated processor costs can be double.
4. Software: The module is delivered with BSPs for a number of different OSs and/or RTOSs. If these have to be developed then the cost can be at least $50,000.
5. Testing: As a rule integrated designs require more complex testing and cost difference can be as much as $30,000.
Bottom Line: The additional costs for an integrated design can amount to $300,000 not counting the costs of redesigns and interest charges. Comments
A long time ago in a galaxy far, far away…embedded devices were single-threaded, standalone, and relatively straightforward to design. Those days are clearly over. With 50 billion connected devices predicted for 2020—the so-called Internet of Things (IoT)—even the most deeply embedded systems will face issues with scalability, modularity, connectivity, and reliability that were far more manageable in the past.
There are numerous on-ramps to the IoT, but choosing between them may require some rethinking. A recent Micrium white paper sorts out the issues and suggests some strategies for integrating your devices into the IoT. More
