Will the base board then be powered through the I/O port?
Or do I need an additional power-slot-module and “bridge” the +5V power from the 19018 to input of the power-slot module?
Asking because I had no success at the first attempt. Connected a PoE-enabled LAN cable, but the base board and modules showed no signs of life. Working on meshtastic, btw.
You will need an additional cable from the 5V output of the PoE board to the solar connector of the WisBlock Base Board to power the complete WisBlock setup through PoE.
If you need ethernet connectivity, RAK13800+RAK19018 is what you need then you can use the standard RAK19007 WisBlock Base board to eliminate the need for extra cable since the 5V output of the RAK19018 POE will be provided (ORed) in the VBUS line. On you current RAK19010 Base Board, the VUSB is not connected to the RAK19018 POE output so you will need the Solar cable.
I can enable POE on my WisBlock Base boards (RAK5005-O and RAK19007 boards) without the need of the cable connected to solar connector input.
