Universal Audio Apollo Thunderbolt 3 Option Card

This option card fits the card slot in a rackmount Apollo interface and replaces its connection with two Thunderbolt 3 ports, which is how an older rack Apollo keeps working with a current Mac or PC.

The two ports allow daisy-chaining further Apollos or other peripherals, carry 40 Gbps of bandwidth for devices including 4K displays and drives, and supply 15 W of bus power downstream.
