Bringing the Convenience of Raspberry Pi to FA and Measurement Control

Unique! Raspberry Pi Solutions from Contec

Expanded the original HAT specifications to allow stack connections of up to 8 cards

Connect up to 8 cards

FA control and measurement control systems require large numbers of signal inputs and outputs. Where previously only a single card could be connected, Contec has expanded the HAT (Hardware Attached on Top) specifications to allow multilevel connections. Our original Board ID system allows a maximum of 8 cards to be connected in a stack for use with systems that require multiple signal inputs and outputs.


Utilize all valuable development assets with multi-platform support

Easy replace

Do you want to replace part of a PC-based system with Raspberry Pi? Do you want to scale-up a Raspberry Pi-based system to a PC-base? Contec makes these changes possible with a minimum of program changes. Integrated driver software minimizes the effects of hardware differences, ensuring high compatibility on the API level.


Contec has the solution for measurement control in every age

Support PythonSupports the popular IoT languages Python and Linux standard gcc. Contains multiple sample programs.

allows connectionThe CPI Series includes a convenient terminal block that allows connection and disconnection of wired HATs, as well as push-type terminals for tool-free wiring.

Embedded with Raspberry PiEven if it is Raspberry Pi, you want a sturdy assembly, right? Accessories for practical installation are available.
