An open source project for underwater sensor nodes based on single-pair Ethernet technology SPE (from tutorial to actual combat, English)

 
Overview
A prototype project designed to build an underwater sensor node powered by a single pair of Ethernet and communicating with the water surface. Single-Pair-Ethernet technology (SPE, Single-Pair-Ethernet) describes the transmission of Ethernet through only a pair of copper cores. In addition to transmitting data through Ethernet, it can also simultaneously provide power to terminal devices through PoDL (power supply over data lines).
