Actisense NGT-1

It's a USB to NMEA2000 adapter. USB side is an FTDI chip. FTDI talks to an ST STR712FR1, then an isolation barrier, and CAN interface (NCV7351). CAN side of isolation appears to be powered from the CAN bus. There is very little to it, but it is all spread out a lot in an excessively large box.

The microcontroller core is an ARM7TDMI, which is a pre Cortex-M design, so a predecessor to the STM32s it seems.

The NMEA network cable is quite hefty.

Actisense sell an isolated and non-isolated version. The one I looked at says it is the normal USB version but it appears to be isolated inside.

It could benefit from Conformal Coating.
