Have a look at the Texas Avenger series, schematics and shared Oshpark links. Texas Avenger "TA" Driver series - Triple channel + Bistro or Narsil + Clicky or E-switch - The Ultimate open source driver!
Harley Quinn and Del have released things here as well.
Be aware good 7135’s are hard to find. Mountain Electronics and LCSC are the last two places I bought good ones from.
