Kunbus RevPi Flat S

SKU #: KU-PR100371

This is a new item expected to ship in late Q3 2022. We are now accepting pre-orders. Please email or contact us for updated lead times and availability.

A Slim Compact Controller Based on Raspberry Pi 

RevPi Flat is an open source industrial PC for the DIN rail. Equipped with the Raspberry Pi Compute Module 4S, the device has a 1.5 GHz quad-core processor with 1 GB RAM and 8 GB eMMC flash memory. With its slim design, it fits perfectly into the sub-distribution cabinets that are typically used in building automation. The operating system used by the RevPi Flat is a specially adapted Raspbian version with RT patch by default. Unlike the RevPi Core and RevPi Connect devices, the RevPi Flat is not modular in design and cannot be extended with expansion modules.

Ideal Applications:

- Decentralized Energy Management
- Virtual Power Plants
- Energy Trading
