This connector provides the position-compare outputs and the amplifier enable outputs for the four servo
interface channels. The board is shipped by default with a ULN2803A or equivalent open-collector driver
IC on U37 and U53. It may be replaced with UDN2891A or equivalent open-emitter driver (E101-E102 or
E114-E115 must be changed), or a 74ACT563 or equivalent 5V CMOS driver.
