Contec Co., Ltd. (listed on the Second Section of the Tokyo Stock Exchange, Securities Code: 6639) has developed new HAT size cards (7 models) for utilizing Raspberry Pi® computers in factory automation and measurement control applications. These cards will be introduced as the CPI Series on April 26, 2021.


Developed to promote computer science studies, Raspberry Pi computers have become incredibly popular since their introduction in 2012. The devices have grown to become a major computer platform with more than 37 million*1 cards being shipped across the globe. The Raspberry Pi is widely used in the industrial and academic fields. According to the Raspberry Pi Foundation, as of June 2018, 60%*2 of monthly device production volume has been for industrial applications.

The 40-pin GPIO pin header connector of a Raspberry Pi computer can be used for adding functionality through stacked connections to HAT (Hardware Attached on Top) expansion cards. In the past, dedicated HATs were designed for specific projects such as education or experimentation. The HAT specification allows only single-card stacking, however, making applications in measurement control fields difficult due to the different I/O points of each system and the wide variety of signals being handled.

Contec’s new HAT size cards solve this problem by expanding the HAT specifications with multi-stage connectivity for general-purpose usability. The simultaneously developed general-purpose RAS function expansion card that adds industrial computer availability and maintainability to the Raspberry Pi also introduces new application scenarios for Raspberry Pi devices.

Under the motto of “Bringing the ease of PCs to FA,” Contec has been both a pioneer and industry leader in PC-based measurement control systems since the introduction of the first personal computers. Contec is reaffirming this dedication with the new CPI Series of Raspberry Pi HAT size cards. The lineup is expected to be further expanded in summer 2021 with analog input, analog output, temperature sensor input, and counter functionality.
