## Description

The BE-IIS HPP-T1S is a stackable and detectable Technology HAT for Raspberry Pi, adding a 10BASE-T1S Single-Pair Ethernet signal port to Linux-based prototypes, gateways and test systems.

It is built around the LAN865x 10BASE-T1S Ethernet controller and provides a dual-connector interface for multidrop SPE networks. The board can be stacked multiple times — for example three HPP-T1S boards, or combined with other BE-IIS Technology HATs in the same Raspberry Pi system.

A PoSPE Power Injector Daughterboard (BE-IIS-HPP-PoSPE) is also available, supporting Power over Single-Pair Ethernet up to 33 V and 1 A for powered multidrop applications. It can be ordered with this HAT by selecting the PoSPE variant above, or separately from the Tindie store.

The open-source BE-IIS Installer configures this HAT—and all other HATs in the BE-IIS portfolio—in minutes, without requiring in-depth Linux knowledge.
