Note: 3CDC-LC-MB Module is mechanically the same as 3CDC-LC Module except the \
schematics, layouts & electrical parts list related to the CDC Board.The CDC Board (recognized by 12NC :\
3103 303 34522 printed on the Board)
is introduced as an alternative to supplement for the shortage of Servo \
IC TDA7073A.
