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.

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.
