schematics

[nik sinclair]

HI
i have a bb2 with a blown motor drive....i am an e engineer so i can fix it if i can get a look at the schematics for this section.
Reverse engineering it is sooo time consuming and prone to errors because i have missing smd bits and some track damage.
So a small section of any motor drive diagram would be most helpful.....just the layout and connections between drive chip, controller and associated small components involved with filters and power monitoring .... please ......
Regards
Nik Sinclair.
