Power over SPE (PoSPE) Industrial HAT++ Add-on for Raspberry Pi
Datasheet Schematic 3D Model Layout
Proprietary PoSPE board enabling power sourcing and delivery over Single Pair Ethernet (SPE), derived from established design approaches and industry practices.
This board extends BE-IIS HAT++ 10BASE-T1S and 10BASE-T1L HATs by enabling Power over Single Pair Ethernet (PoSPE). It is fully transparent to the BE-IIS HAT++ ecosystem, does not affect stackability, and instead enables power delivery for stacked systems, supporting seamless system integration and scalable system expansion.
