KUNBUS introduced the latest additions to the Revolution Pi (RevPi) family in 2022: The S and SE series, which are based on the custom-made Raspberry Pi Compute Module 4S. The series represents a transitional step between the 3+ series and the upcoming RevPi 4 series.
The global chip shortage affected the availability of compute modules, so the Raspberry Pi organization offered KUNBUS a special alternative to the Compute Module 3+: The Compute Module 4S. This is a custom-made module that has the same form factor as the CM 3+, but features the more powerful Arm Cortex-A72 processor of the CM 4.
The difference between the S and SE series is simple: The S series is compatible with all expansion modules including our fieldbus gateways. The SE series can only be extended by IO modules and in case of the RevPi Connect by Con modules. Fieldbus gateways are not supported in the SE series.
