In order to support a test at an Ameriflux monitoring station, we need to create a version of the Frog Sensor that supports Power over Ethernet (PoE).
@damz has been doing good work supporting a Power over Ethernet module in Software, but we will need to modify the enclosure to support this as well.
Hardware Selection
The PoE Featherwing from Silicognition is the selected hardware that allows data and power over the ethernet connector in a featherwing form-factor.
This board can be purchased from several places:
@keenanjohnson and @damz both have testing modules.
Enclosure Modification
@damz provided the image below showing that the board will obviously not fit in the current enclosure.
It seems that the enclosure will need to become deeper to support the added height of the ethernet connector.
The other big decision is whether to turn the microcontroller and PoE hat so that the cable comes out of the bottom or route the cable out of the side of the enclosure using a cable gland.
Scalability
This design is initially for a one-off test, so I'm not so worried about it being easy to produce or anything.
