Lego doesn't but Charmed Labs does and Botball uses it.
Charmed Labs
Botball uses this interface exclusively now for their competition replacing the Handyboard system with each team receiving two of these in their kit. I believe the only place one can buy it though is via botball as the store on the Charmed labs site has listed them as out of stock for at least six months now.
XBC robot controller electronics
This controller uses pwm type pin sets for motor and sensor connections. One can clip the ends of the standard lego connectors and solder a new connector. If you clip the lego wire in the middle you get two, a bit shorter, motor connectors.
