The other 3 signal pins are all free because of the rotation. The remaining GND pins are internally connected in the TPIC. | The other 3 signal pins are all free because of the rotation. The remaining GND pins are internally connected in the TPIC. | ||

(so basically, don't put any motors on the middle pins 7, 8, & 9, or on 14. The strange shift is because of skew in the HEF part) | |||

I have mine working now except for the motor order (need to change the code to match my new armature). So it does work, and other than the desoldering it's actually not too much work. | I have mine working now except for the motor order (need to change the code to match my new armature).
