In every autonomous subsea vehicle, particularly those with modern architectures involving distributed subsea control, actuation, and sensing systems, there are common “utilities” needs that arise.

We have developed a COTS AUV utility card that solves many of these problems in one compact PCB. The Stone Aerospace LDPCB is a microprocessor controlled system containing the following on-card features:

• leak detection through relative humidity sensing
• 4 12-bit resolution analog inputs
• 2 Form-A 10A relays
• 5 CMOS compatible digital outputs
• 2 Form-C 3A relays
• 2 8-bit resolution analog outputs
• 2 open-collector outputs
• 2 logic outputs
• RS485 communications link to host computer (up to 16 boards may be placed on the same link)
