PR100360 RevPi Core S 16 GB

Open source IPC with 8/16/32 GB eMMC based on Raspberry Pi

General

The RevPi Core is with 22.5mm only half as wide as the RevPi Connect, but has twice as many PiBridge connectors, namely two. Thus, the RevPi Core can be upgraded with up to 10 expansion modules. Like the RevPi Connect series, the RevPi Core series is also equipped with the Raspberry Pi Compute Module 3, Compute Module 3+ or Compute Module 4S, depending on the variant. A Real Time Clock (RTC) with 24 h buffering ensures that the device always knows what time it is, even in the event of a power failure. As with all Revolution Pi base modules, a specially adapted version of Raspbian with real-time function is used as the operating system.

Core S / Core SE The new Revolution Pi S/SE series are updated base modules of the open source IPC, based for the first time on the Raspberry Pi Compute Module 4S. The new series are positioned between the 3+ series and the RevPi 4 series and are intended to compensate for the supply shortages of the Compute Module 3+. RevPi Core, RevPi Connect and RevPi Flat are available as S/SE series. The Raspberry Pi organization offers the Compute Module 4S as an alternative to the Compute Module 3+, which is currently difficult to deliver. This is a Compute Module in the form factor of the CM 3+, on which the more powerful Arm Cortex-A72 processor of the CM 4 is installed. The S-Series differs from the SE-Series in its compatibility with expansion modules, including fieldbus gateways. The SE series, on the other hand, can only be expanded with IO modules and, in the case of the RevPi Connect, with Con modules. Fieldbus gateways are not supported in the SE series. This innovation is also based on the worldwide semiconductor crisis: The required Ethernet IC, which is responsible for connecting the gateways via the PiBridge, is currently not available in sufficient quantities. Since many operate the devices without gateways, the SE series was created to ensure that enough devices can be built to meet all customer requirements. The new CPU of the Compute Module 4 S is only supported with kernel 5.10. Customers using their own image or a KUNBUS image with an older kernel must update the kernel. Detailed migration instructions are available from KUNBUS.

Important notes:Alternative to PR100300 - expandable with I/Os and gateways.
