Hi all,
while sorting out my current problems, I am also thinking about new ones. Or at least about cool new features for my projects
Using the Teensy 4.1 on a breadboard made me think of a custom PCB where also the Ethernet connector could be placed directly onto the PCB.
As I am not a pro designer for high speed data lines, my assumptions are:

Using the Teensy 4.1 on a breadboard made me think of a custom PCB where also the Ethernet connector could be placed directly onto the PCB.
As I am not a pro designer for high speed data lines, my assumptions are:
- From the six pins, RX +/- need to have the same length and TX +/- need to have the same length.
- I see from https://www.pjrc.com/store/ethernet_kit.html how the wiring needs to be done. Is it important what type of capacitor is used or can I use any as long as it has 0.1μF? E.g. an SMD one directly soldered by the PCB factory.
- If the rx/tx lines are on the front side of the PCB, do I have to take special precautions regarding the back side of the PCB? Usually, I put my ground there and make it as big as possible.
- As the ethernet pins are in the middle of the board, I might consider leaving out some of the side pins so routing gets easier. Any objections regarding this approach?
