Products > SPE HAT / SPE HAT mini

Single Pair Ethernet 10BASE-T1L board for RaspberryPi

Product Overview

SPE HAT / SPE HAT mini is an expansion board that can turn RaspberryPi into a single pair Ethernet 10BASE-T1L terminal. The SPE HAT is a standard size RaspberryPi HAT and the SPE HAT mini is a RaspberryPi zero HAT.

10BASE-T1L (IEEE 802.3cg-2019) and Ethernet-APL are new standards to replace conventional field networks such as RS485, enabling all industrial networks to be Ethernetized. The standard transmission distance is 1000m, and it supports a transmission speed of 10Mbps and power supply up to 52W by PoDL/SPoE. It also supports intrinsically safe and is expected to be introduced in plants in the future.

Linux driver for Raspberry Pi OS

A Linux driver for this product is available on GitHub, please refer to the GitHub repository below for instructions on how to build and install on the Raspberry Pi OS.

SPE HAT mini Movie Demo

A demo video of the prototype version of this product is posted on Youtube. The SPE HAT mini is connected with a 200m rough twisted wire and the camera image is transferred. Longer distances can be transmitted using proper twisted-pair cables that take into account their characteristic impedance, but it still yields speeds of 9.1 Mbps. A driver for Linux will be released at a later date.
