You would need to contact the module manufacturer.

But remember that they are under no obligation whatsoever to release such information - unless they have specifically stated that it is "open hardware" (in which case, surely, they would have given details of where to find the design files?)

Here: www.waveshare.com/.../Core51822_(B)

And development board: www.waveshare.com/.../BLE400

That doesn't appear to be quite the same board - the layout (which the OP specifically wanted) is certainly different!

Yes I posted it to quickly, here is the good one: www.waveshare.com/.../Core51822
