Good news everyone! But no, it is not yet the RevPi 4 but the RevPi S/SE-series.
Today we are happy to present you the newest members of our Revolution Pi family: The S and SE series, based on the brand-new Raspberry Pi Compute Module 4S. The series are an intermediate step between the 3+ series and the RevPi 4 series. In the following paragraphs, we will explain why this is necessary, the technical details and why Revolution Pis with the Compute Module 4 are not available yet.
As you know, the Revolution Pi family was not spared from the global chip shortage. In the last months we had to put many customers and people interested in RevPis off. This was mainly due to the supply of compute modules, which could not be delivered sufficiently.
The Raspberry Pi organization has therefore offered us a special alternative to the Compute Module 3+: The Compute Module 4S. This is a Compute Module in the form factor of the CM3+, on which the more powerful Arm Cortex-A72 processor of the CM4 is installed.
The following modules will be available as S/SE series: RevPi Core, RevPi Connect and RevPi Flat.
What is the difference between the S-series and the SE-series?
The difference between the S and SE series is quickly explained: 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.
What was the reason for developing two series?
This alteration is also based on the global chip shortage: The required IC, which is responsible for the connection of the gateways via PiBridge, is currently not available for us in adequate quantities. As we see from the sales figures, many RevPi users operate their devices without gateways: Therefore, we have decided to launch the SE series in order to make sure that we can build enough devices for every customer requirements.
Is there anything to consider when upgrading from the previous devices to the S or SE series?
Customers who switch from devices with the CM3/3+ to RevPis with the CM4S must note an important change. The new CPU of the Compute Module 4S is only supported with the kernel 5.10. Customers using their own image or a KUNBUS image with an older kernel must update the kernel. To learn more about how to do this, click here.
RevPi 3/3+, 4 and S/SE: When can what be delivered?
Our Revolution Pi base modules with Compute Modules 3 or 3+ will remain in the portfolio. We hope that the delivery situation of the Compute Modules 3/3+ will improve in the next few months.
