I can make that board using more easily available parts - you could test it then I could add it to my range of re=created boards.
The main problem with pin sellers being out of stock of a lot of things these days is that heaps of the parts used have become obsolete. In the case of this PCB the bridge driver IC is hard to find and EXPENSIVE when you do. I would use a very similar part but from new production.
Let me know Andrew.
