The design for a 4-servo driver board is complete.  One of these boards will drive each leg of the BuckyBot (it has 6 legs).  Servos will be GS90's.  Three servos for leg joints (up to 3) and one servo for leg abduction/adduction.  Using a quad LED driver (LED drivers have multiple PWM outputs) to control the rotation of servos.  Board is tiny.  Will be posting design information at www.ranarchy.org this weekend.  Stay Tuned.
