Single Pair Ethernet 10BASE-T1L board for RaspberryPi


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.

Our Business

Software development

Software development

Our specialty is the development of embedded software and firmware for microcontrollers. We also develop software for Windows, Linux and smartphone apps.

  • Firmware for microcontrollers
  • Driver for sensors and peripheral hardware
  • Software and driver that runs on a specific OS for single board computers
  • PC software and Web applications for embedded device control
  • Collective development including hardware specification, design and evaluation

FPGA development

FPGA development

Prototyping and mass producing hardware using FPGAs is our specialty. We have achieved many successes with Intel (Altera) Cyclone Series, Xilinx ZYNQ and Spartan Series, and MAX V/ MAX10. We have a business partnership with J-7 SYSTEM WORKS Co., Ltd. in Japan, and are authorized distributors of various FPGA boards.

  • Logic design by hardware description language such as Verilog HDL / VHDL.
  • Development of original IP cores for high-speed I/F, image processing systems, and other peripherals
  • Verification work of IPs provided by other companies and other IPs
  • Selection and proposal of FPGA that matches the customer's application

Hardware design

Hardware design

We are also designing hardware, so we can respond to a wide range of requests from hardware to software quickly. We provide support from trial production to mass production, new designs, as well as customization.

  • Circuit design and board design
  • Hardware performance evaluation and verification work
  • Customization of customer's existing products
  • Proposals for selection of electronic components and modules, board mounting

Case studies for development



Jointly developed with TRA, which develops the Cheero brand famous for mobile batteries in Japan. We were responsible for the trial development of internal circuits, focusing on the fantastically shining three-color LED illumination part.

Business in charge:

  • Circuit design (illumination part, power supply part)
  • Firmware development

Cheero Sleepion (First model)

Cheero Sleepion

As the second joint development with TRA, we had entrusted with everything from equipment specification formulation to circuit / board design and firmware development. We had also supported mass production including inspection jig development and performance evaluation. Currently on sale at Amazon.

Business in charge:

  • Equipment specification formulation
  • Circuit design (digital and analog circuit)
  • Board design (prototype board, mass production board)
  • Microcontroller firmware development
  • Performance evaluation, reliability evaluation
  • Inspection specification formulation, inspection jig development

Digital signage system

Android porting

We developed the digital signage system was conbined with an industrial touch panel and ARM-SoC single board computer. It is running the latest version of Android-OS (Android 8.1) at the time.

Business in charge:

  • Selection of single board computer
  • Linux and Android-OS (AOSP) porting
  • Linux device driver development

Hot water control system by FPGA on railroad vehicle

FPGA power control

Power control of vehicle equipment installed in luxury sleeper train "Twilight Express Mizukaze" currently running in western Japan is realized using a processor on FPGA and our software.

Business in charge:

  • FPGA logic design (Altera CycloneIV / QuartusII)
  • Nios II firmware development

Replacement of old/discontinued MCUs with FPGA

FPGA replace system

We create a new and scalable system by emulating the old or discontinued microcontroller and its peripherals with an FPGA.

Business in charge:

  • FPGA logic design (Xilinx Spartan-6 / ISE)
  • Development of FPGA configuration tool for Windows (Java)
  • Program development by Z80 assembler

Other cases

  • Smart lock system (Firmware development of Bluetooth-LE MCU)
  • Debugging DDR memory access for automotive testing FPGA Boards
  • Jet engine characteristic measurement equipment and control software for Windows
  • FPGA board development for thermal printer control, software development for Nios II
  • Smart speaker cooperation device (circuit design and firmware development)
  • Remote monitoring/control system for industrial equipment
  • Inspection jig for semiconductor devices equipped with high-speed I/F
