Trying to map out an internal subassembly with this board, but can not find any 3D schematic (heights of elements on board) as well as through hole diameters for mounting in the product description page.
Sparkfun doesn’t have 3D files for most of their products, especially the newer ones.
You need to load up their Eagle files in Autodesk Fusion (which you can still get for free) and from there you can create 3D your files. You can also view board dimensions from within Eagle which is part of Autodesk Fusion.
