The sensor infrastructure supports Tachyon's various sensors, including the serial communication used between sensors and the computer.
The Serial Board allows Tachyon’s computer to communicate with peripherals such as thrusters, sensors, and power boards. It takes in a USB 2.0 Hi-Speed cable from the computer via a standard female type B USB connector and provides 14 RS232 serial ports each by a 3 circuit Molex Microfit-3.0 connector. The USB signal is first split by a SMSC USB2507 7-port USB hub and each of the 7 signals are then split again through 1 of 7 FTDI FT2232D dual-channel USB to RS232 adapters.

| The General Purpose Input/Output Boards (GPIO) give Tachyon a great deal of flexibility: they allow analog and digital sensors and devices to by added in without additional infrastructure. This allows easy addition on devices to improve vehicle functionality. The Analog GPIO (AGPIO) board is used to handle analog inputs, such as that from a pressure transducer for depth. The Digital GPIO can be used to control digital devices, such as the LCD that displays vehicle status in the hull.
