As i am currently designing a project involving a stm32f446ve that requires semi good timing, I am looking into using a crystal oscillator.
As this is still an early prototype, I would like to be able to fit as many different crystals as possible, and after some research determined the 3.2 x 2.5mm footprint is perfect for my need as it is also fairly small.
However, there are slight differences in the pin out. Namely, some wire the crystal itself to the bottom left and top right pin, while others wire it to the bottom right and top left pin. As an example:
To be able to use both, I though it might be a good idea to connect both pins on either side, to connect to the crystal no matter what pins on that side it is connected to. However I have never worked with crystals before and am not sure if shorting the two pins on either side of a crystal is a good idea. As far as I can see however, the pins to which the crystal is not connected are also not connected to anything internally.
