+### Two of our nodes connected on wall plugs at LIG (IMAG building)
+
+The upper one is a Raspberry Pi 3B+ with a PoE Hat in its case.
+The lower one is a PCEngines APU, PoE-powered too thanks to an external PoE splitter (black box next to it). This kind of node has 3 wired ethernet plugs so we use one for the WalT network and two more are available for experiments.
