Thanks!

Nominal distance (Dimension M1 in STM Datasheet) between both rows of pins is 5.08mm. In this model is 4.507mm which is under minumal dimension (4.63 ...

Good model, but the distance rear rows of pins from back plate is incorrect.

but there are dimensional errors

Good model, but the distance rear rows of pins from back plate is incorrect.

Me ahorraste un dibujo, eres lo máximo ;)

Good model, but the pitch between the front and rear rows of pins is incorrect.

It looks like the max value from the datasheet is used for the pin pitch instead of the typ. one

Typical pin spacing between rows should be 200 mils (here is 177)
