The modular architecture provided by FLEX allows to compound a number of boards to integrate different features into a single device.

The basic configuration of a FLEX device is made by the main board only. The FLEX Base Board mounts a Microchip dsPIC® DSC micro-controller, and exports almost all the pins of the micro-controller. The user can easily connect the desired components to the dsPIC® DSC ports in order to build the specific application.

As depicted in the Figure, several daughter boards can be connected in piggyback to the FLEX Base Board. The daughter boards have different features and they can be easily combined to obtain complex devices. Evidence Srl and Embedded Solutions supply a growing number of daughter boards for basic and advanced applications.
