Now stick the header through the underside of the Arduino Pro Mini. Make sure the six wires are in the correct order. In my set-up, the Orange wire happens to be "DTR" from the serial adapter, so I have ensured that it mates up with the pin labelled "DTR" on the Arduino. The colours of other cables will be different from this one. Lay the assembly down as shown, and lightly apply pressure to the Arduino/header so that it makes contact. Keep a finger on it while uploading the program to it from the Arduino IDE. Begin the project assembly, by stacking three layers of 3M black mounting tape onto the ethernet module: one layer between the RJ45 jack and the W5500 chip, and then two more layers on top of that and the chip. This creates a flat surface onto which the Arduino board can be placed. But first, add a bit of electrical tape over top of the silver crystal as well, to prevent short circuits. Top view of the mounting tape and crystal with translucent electrical tape on it. Here is the Arduino Pro Mini board (5V/16MHz) stuck on top of the mounting tape. It has deliberately been placed off to one side, so as not to overly obstruct the wiring points for the ethernet module underneath at top right. Now stick more mounting tape to the flat side of the DC-to-DC buck converter, which one should already have adjusted for 5.8V output. If not, it may fry the Arduino board later when first powered-on. Stick the DC-to-DC buck converter on top of the Arduino, being careful not to obstruct any of the signal holes, and also avoiding the (red) reset switch area. This is what it looks like once all stacked together with 3M mounting tape.
