Abstract
Abstract An innovative microboard package, which includes not only a row of edge connector contacts along one long edge thereof, but also includes another row of edge connector contacts along the other long edge. The contacts are connected so that the functionality of the board can be changed merely by choosing one of the two orientations for insertion. For example, one embodiment provides a microprocessor module if insertion is done in one direction, and a microcontroller module if insertion in the other direction. Optionally, the row of contacts which is not inserted into the mother board can be connected to a jumper cable, using a simple connector header.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
177 words
A microboard package for an electronic subsystem, comprising: a microboard having first and second long edges, and one or more shorter edges, around the perimeter thereof; said first long edge having a first row of edge connector contacts along substantially all of said first long edge, and said second long edge having a second row of edge connector contacts along substantially all of said second edge; said shorter edges without connector contacts; said first and second rows of edge connector contacts being configured so that either can be inserted into a female connector in a motherboard; said first and second rows of edge connector contacts having substantially the same physical layout, but not having substantially the same electrical contact placements; whereby a user can choose a first functional connection to a motherboard female connector of a given form factor by inserting said first row of contacts into said motherboard female connector, or alternatively can choose a second functional connection, different from said first functional connection, by inserting said second row of contacts into said motherboard female connector.
Claim 2
Dependent Claim
