3 Architecture
The modular architecture provided by FLEX allows to compound a number of boards to
integrate different features into a single device.
Base Board mounts a Microchip dsPIC (R) DSC micro-controller, and exports almost all
the pins of the micro-controller. The user can easily connect the desired components to
the dsPIC (R) DSC ports in order to build the specific application.
to the FLEX Base Board. The daughter boards have different features and they can
be easily combined to obtain complex devices. Evidence S.r.l. and Embedded Solutions
S.r.l. supplies a growing number of daughter boards for basic and advanced applications.
3.1 Base board
The FLEX Base Board is designed to export all the connections of a standard Microchip
dsPIC (R) DSC micro-controller. The board connections use the standard 2.54 mm pitch:
this feature make it easy the usage of custom, home-made daughter boards.
dsPIC (R) DSC controller welded on the board surface, and a socket for installing the
micro-controller through the interchangeable Plug-In Modules (PIMs) available from Mi-
crochip. The availability of the latter option allows the developer to forget any limit on
the number of programming cycles during the implementation/test/debugging phases:
a new PIM can be installed on the socket in case of any problem to the older one.
application developed with the Full Version can be easily moved to the Light Version
and vice-versa, i.e., without any modification to the control program.
3.1.1 Base board: Full version
The Full FLEX Base Board, depicted in Figure 3.3, integrates an extra-robust power
supply circuitry, which allows the usage of a wide range of power suppliers.

The board have two options for using onboard dsPIC (R) DSC micro-controllers:
The FLEX Base Board is available in two versions:
The connectors are fully compatible between Full and Light Versions, so that an
