Any 4 pin connector should work, but to avoid noise issues you'll probably want to use twisted pair shielded wire, carry the shield through the connector, and depending on the total length of the cable run, 28 to 20 AWG wire (0.81m to 5m length, according to USB 2.0 spec).<br><br>Sean<br><br><br><br>Sent from ProtonMail mobile<br><br><br><br>-------- Original Message --------<br>On Nov 30, 2017, 18:03, Brian Cox via Personal_Submersibles < <a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:</div><blockquote><br><div style="font-family: Arial, sans-serif; font-size: 10pt;"><div>Hi All,</div><div> Has any one ran usb cable thru the hull and out to a camera or other device?
