This article features the PaPiRus, the Pi PoE, and the Raspberry Pi 3 to build a portable access point with a screen. We will be working with the Pi PoE, but everything in this tutorial can be achieved without it, too. This tutorial assumes your version of Raspbian Jessie is up-to-date.
PaPiRus ePaper / eInk Screen HAT
Pi PoE Switch HAT
TP-LINK PoE Injector (optional)
GPIO adapter for RPi-Display B+ – female
Putting everything together
Building this access point is extremely easy. It requires minimal soldering and for the rest, it’s really just a question of stacking together the various components.
The additional header will allow us to install the PaPiRus on top of the Pi PoE, but we did this via the GPIO adapter.
In some cases, your infrastructure will already be able to deliver Power over Ethernet; if not, you’ll need to use a PoE injector like the TP-LINK TL-POE150S.
Connect everything up, making sure that the flat cable for the PaPiRus is connected the right way around.
Once all is connected and ready to use, a long press on the switch of the Pi PoE module will power up the system.
