A deep dive into Single Pair Ethernet
We built a Power over Data Line (PoDL) compliant device and power supply as part of a one-month &#x27;sink or swim&#x27; approach to designing and testing new hardware, and getting to look at maturity of the 10Base-T1 ecosystem. The board was enclosed a submersible sensor node and field tested at a popular dive reef, SCUBA diving down and mounting it to the jetty.<p>It was also a nice excuse to get some macro shots of the PCB assembly process, including some nice footage of solder paste melting and the interesting surface tension interactions.<p>(I can&#x27;t seem to get the videos to render in a format that iOS Safari will play, if anyone knows the ffmpeg incantation, please let me know, nothing I&#x27;ve tried has worked on my iPhone...)
