All 3.5 mm and 6.3 mm jack plugs of the SEI system can be utilized as either inputs or outputs. Thanks to the color code, mixing up channels is impossible. The 6,3 mm connectors are mounted on a circuit board, which can be easily fastened at the back of the UNO case. The enclosure comes with suitable drill holes, so the sockets can be screwed in place without any problems. No craftsmanship needed.
The USB port is only meant as a +5V power supply for a gooseneck lamp or the like. Data cannot be transmitted using this port.
module: six 3.5mm sockets
board: six 1/4" sockets
