Previous image Up to current index page (1) Next image First step: flash the ethernet sketch (program) into the Arduino. Click here to get it. With a Pro Micro board, simply use the built-in USB port for this. But here, we are using Pro Mini boards, so an external 5V TTL serial adapter is used.Normally, the Arduino would have the six-pin header (shown) soldered in place, but we don't want that here (it gets in the way). Instead, insert the header into the end of the TTL programming cable as shown. 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.
