Germany-based Brechel Electronic has launched two new Single Pair Ethernet (SPE) expansion boards for Raspberry Pi platforms: the BE-IIS-HPP-T1S and the BE-IIS-HPP-T1L. Designed for technology evaluation, industrial network prototyping, and educational laboratory use, these boards add 10 Mbit/s Ethernet communication over a single twisted pair to standard Raspberry Pi SBCs.The BE-IIS-HPP-T1S is based on the Microchip LAN8651 10BASE-T1S MAC-PHY and supports IEEE 802.3cg Single Pair Ethernet over multidrop networks with up to 8 nodes, enabling distances up to 25 meters on a shared bus. For longer-reach point-to-point links, the company offers the BE-IIS-HPP-T1L, built around Analog Devices ADIN1110 MAC-PHY. Both boards are part of the BE-IIS HAT++ ecosystem, which allows multiple industrial communication HATs to be stacked on a single Raspberry Pi without running into SPI or GPIO resource conflicts.10BASE T1S SPE HAT
