 Venus OS extended is also available for certain RaspberryPi models. Installation files below, and installation & other raspberrypi specific instructions [[https://github.com/victronenergy/venus/wiki/raspberrypi-install-venus-image|here]].
+==== 3.2 CPU & Memory resources ====
+Both SignalK as well as Node-red are rather resource intensive software applications to run on the GX Device. From a CPU usage point of view as well as RAM memory.
+Ofcourse, how intensive depends on what kind of flows (node-red) or how many messages & handling of them (SignalK) happens in the system.
+From a GX device point of view, from the support models the Venus GX is the one with the least resources. Running both SignalK and Node-RED at the same time will be "pushing it" to say it simply.
+Cerbo GX is already much faster, as it has a dual core CPU as well as much more RAM.
+More details about CPU & RAM differences are in this document: https://github.com/victronenergy/venus/wiki/machines.
+When running out of RAM or CPU, the device will slow down. And eventually also reboot by itself due to the watchdog.
