The first version of FELINI was a device consisting of 2 larger and rougher circuit boards compared to the current version, and it was not designed with an integrated battery. This means that it could not function without being connected to a laptop, external power source, or powered through the connectors located on the bottom side.

This version was overloaded with numerous complex features and nearly non-functional due to missing components, as some of the parts couldn't be ordered. As a result, it only made it to the stage of 3D-printed casing assembly testing.

The next version was attempted with modified component footprints, but it still didn't work, mostly due to my mistakes and errors during the design process. Therefore, I decided to start a completely new version of FELINI, which is the current version we have now.
