PiVCCU lief stabil durch. In einem zweiten Durchlauf habe ich auch mal WebUI geöffnet und ein paar Geräte bedient, was auch noch gut funktioniert hat.
Zum Vergleich der Reserve-Opi, auf dem "nichts" läuft mit einem provisorischen Inbetriebnhamekühlkörper, der gerade mal das SoC abdeckt

Mit dieser "Vollast" bleibt der piVCCU OPi noch immer unter 50°C bei etwa 24°C Umgebungstemperatur. Der Reserve-Wemos ins in einem anderen Raum bei ca. 20°C.
