RevPi Connect


No appetite for restrictions? Realise your ideas with the open-source IIoT gateway RevPi Connect.


When implementing IIoT projects this open-source IIoT gateway RevPi Connect gives users maximum freedom due to its open platform concept.


RevPi Connect is based on the Raspberry Pi Compute Module 3 and features a 1.2 GHz quad-core processor, 1 GB RAM, and 4 GB eMMC flash memory.  A Real-Time Clock (RTC) with 24h buffering ensures that the device always knows what time it is, even in the event of a power failure. A real-time patch is available as an operating system with this specially modified Raspbian version. Common IIoT protocols like MQTT and OPC UA are supported to transfer machine data directly to the Cloud.

Individual applications can be programmed via, amongst other things, Node-RED, Python or directly in C. The modular design of the RevPi Connect enables the 45mm wide base device to be fitted with suitable expansion modules such as digital and analog IOs, fieldbus gateways and radio modules like for example ones for Bluetooth. The expansion modules can be joined up – plug and play – with the base device via a socket positioned at the top and can be easily configured using a graphical user interface.





X2 Connector

This plug has a relay contact as output and a digital input signal (+24 V). The input is connected to GND.


Status LEDs

The LEDs show you the status of the device. You can find out what the individual signals mean here.


RJ-45 sockets

You have two Ethernet ports that are independent of each other.
Tip: Use an angled plug if small installation depth is important for you.


RS485 socket
Your RevPi Compact has a 4-pin RS485 socket. This allows you to connect e.g. sensors for Modbus RTU.


X4 Connector

This connector is responsible for the main power supply of your RevPi Connect. Also, the watchdog is supplied here and you can activate the watchdog here.

We deliver this plug prewired to you so that you can start immediately. If a change is necessary, you will find a description of how to assign this plug here.

Do not connect the power supply until you have mounted your device on the DIN rail. You can operate RevPi Connect in a voltage range of 12 V-24 V.


USB ports

You have two USB-A ports available. This allows you to connect USB 2.0 client devices (e.g. USB hard drives, surfsticks, etc.) Both sockets together may be loaded with a total of 1 A. It does not matter how the current is distributed to both sockets. For example, you can load one socket with 1 A and not use the other or load one socket with 300 A and the other with 700 A. If you need more than two USB-A ports, you will find a suitable USB hub (PR200001R00) in our shop.


Micro-USB connector

You can connect a USB host system here (e.g. a PC to download software to your device). While this port is connected to the USB host system, RevPi Connect switches to passive memory card mode. This allows a PC to access the built-in eMMC flash memory and store an image there, for example.

Disconnect the micro-USB plug after you have played the software your RevPi Core. RevPi does not start as long as the micro-USB connector is plugged in.

Attention! Micro plugs are mechanically sensitive (you know this for sure from your mobile phone charging socket). Therefore you should never work with force and never tilt the plugs, but always insert them without much force. Never bend inserted plugs to their sides and only pull them straight out of the socket.

MODBUS Capability

RevPi Connect already has master and slave capability for the popular Modbus RTU and Modbus TCP network protocols. External gateways are therefore no longer required for these two network protocols. Modbus TCP works with the Ethernet interfaces available on RevPi Connect (i.e. via the RJ45 sockets on the front panel) or any other added Ethernet connection (e.g. USB WLAN adapter) that provides the TCP/IP protocol. Modbus RTU can be realized via the 4-pin RS485 connector on the front panel. The master and slave configuration is controlled via the browser-based, graphical configuration software PiCtory.
