Here, RED is the Buck output, and BLACK is GND.The mode switch also gets wired now, by soldering the bottom pin to the side of the RJ45 or to any other convenient GND point. The middle wire is connected (GREEN) to Arduino Pin-8.I have added a bit more translucent electrical tape between the switch and the RJ45 jack after doing this, to prevent future accidental shorts there. Another view of the fully wired ethernet/Arduino combination. Note that I used thicker wire than necessary for some of the power connections. The skinny stuff would have been fine everywhere. Top view of the ethernet connections. Bottom view, showing the INT and NC pads with no wires attached -- those don't get used in this project. Also notice how all of the protruding pointy bits have been snipped flush on everything on the underside. This way they won't stick through the heat-shrink tubing when it gets added in the final step (much later). Overview of everything accomplished thus far. At this point, the module is ready for early testing, if desired. Connect +9V or +12V to the Buck converter -- you may have to temporarily solder wires on to accomplish this. When powered, several RED LEDs should light up immediately. If not, then disconnect the power and search for wiring errors on the RED and BLACK wires. To test it further, power it off, ensure the "mode switch" is in the UP ("off") position, and Connect an ethernet cable between the module and a computer, and then power it back on again. If all is working, the computer should "connect" to this "new network" and be assigned an IP Address of 1.2.3.5. If not, then something is not wired correctly. Now to wire up the AUX port interface. Begin with the diode, stripe DOWN, into the TXO hole on the Arduino board. Then a 51K-ohm (give or take) resistor into the Vcc hole on the opposite edge of the Arduino board. Twist the resistor around the stiffer diode lead, and solder all three connections.
