The open source IIoT gateway RevPi Connect gives users maximum freedom when implementing IIoT projects due to its open platform concept (including full root rights). RevPi Connect is based on the Raspberry Pi Compute Module 3 and features a 1.2 GHz quad-core processor, 1 GB RAM and up to 32 GB eMMC flash memory. 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. A specially modified Raspbian version with a real time patch is available as an operating system. Common IIoT protocols like MQTT and OPC UA are supported to transfer machine data directly to the Cloud.
