Don Pimpolho is in version 2.1, It was born in 2012 and designed at Altium Designer and Inventor. Its differential is the shape of the board that was developed by the Inventor software (because it was not possible to make that type of board in Altium). It is separated in body, sides and head, where are all analog sensors (eight in total), the side sensors are digital, so faster. Other versions of it were projected as the 1.0 (that didn’t leave the paper) and the 2.0 (that had a problem with the center of gravity).
