3d case

yay fusion is my best friend! this totally hasnt taken like double the time i thought it would?

This was easy, because this is like the 50th time im making a case for a module so i did it quite quickly.

v2 ig?

So i rerouted the entire thing... 3 TIMES! Genuinely why is ethernet so frickin hard. Simon recommended that i expand the expansion module (ba dum tss) so i made it longer so that everything would fit correctly, so now the module is longer, and will hand off of the console, but whatever! I added label boxes in the schematic, but this was mostly changing the pcb.

Instead of having two ground planes, i made one inner layer 3v3 so that it would be easier to route. This time, differential routing was top priotiry, and I learned how to use the diff pair routing in kicad.

I now only have the entire 3d case left to do.

The PCB

So this was extremely hard. Placing so many parts in such a tiny space is really much harder than it seems... So I struggled placing them all into this tiny box, but somehow did it, or so i thought... Turns out, drc didn't like that the chips corner was 0.2mm too close to the edge, so i had to reroute every single trace on that board after i moved the chip 😭.

Schematic

I created the schematic in class, and it took a little while for me to pick the parts I wanted to use, but by the end, I picked the w5500 and a default Ethernet port. I created the schematic basing off of the published w5500 example schematic.

Now time for the PCB
