These are commercial items that are used for a month or less then discarded. I think the customer price is in the $5 to $10 range. Obviously even $.05 per unit production cost can make a meaningful difference. It should be no surprise, but there is far more engineering in the production of these things than in their design. I alone spent more time on the production tester electronics and firmware than on the units themselves, and there is another engineer that only works on production matters and hasn't done any design of these units. By the way, those testers are at the other end of the spectrum. So far I think only 4 testers boards have been produced, although there will probably be a few 10s made over the life of this product. For a project I'm working on today we created just 3 copies of a particular design the customer wanted. These are essentially USB interfaces for live data gathering from another gizmo for testing, debugging, and research. In that case we built them by hand by adding a few parts to our ReadyBoard-02 (http://www.embedinc.com/products/ready02). ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
