The schematics file provided in the site matches for VIM board (http://www.mediafire.com/file/g23br7h202o8g8r/Vim_V12_Sch.pdf) but for VIM Pro I am unable to get the schematics and other mappings. Please suggest link to VIM Pro boards as well.
It should be the same VIM variants only differ in eMMC size (8GB vs 16GB) and WiFi chip (AP6212a vs AP6255).
Indeed. Schematics are the same.
