the description of this modules mentioned old and new versions But is
there any way to physically/visually distinguish these For the older
version it says:

"the pressure sensor is made with conductive rubber located below the
position sensor and works not as accurate as the very precise position
sensor. The resistance of the conductive rubber changes with varying
pressure and causes a variable voltage. But the coherence between
pressure and resistance/voltage is not very accurate - except that an
increasing pressure will cause an increasing voltage. Even some
difference of the pressure sensor behaviour over the length of the
manual may be possible as the conductive rubber has tolerances over this
length."
