I want to use a chip that is only in "wson-10" packaging.
I have not used wson-10.
A few searches came up empty on the size/pin spacing to see if I can use a soic or ssop or other breakout board for proptotyping. Or better, someone knows of a wson-10 breakout board pre-made?
Hi,
Look at the data sheet link provided by mouser, look at the last couple of pages and that will give you the physical chip dimensions.
This link will help.

Then gargle the other sizes and check the dimensions.
