RevPi Connect 4

RevPi Connect 4

The fourth generation of the RevPi Connect is equipped with the Raspberry Pi Compute Module 4.

Its quad-core Arm Cortex-A72 processor and with up to 8 GB of DDR4 RAM, the RevPi Connect 4 gets a significant performance boost over its predecessors and enables use in entirely new application areas. Due to its modular design and integrated interfaces, the RevPi Connect 4 can be used for a wide range of tasks, be it as a pure industrial PC, industrial controller, edge gateway or IIoT device.
