    Teensy 4.1 Ethernet pins + socket

    I am making an addon pcb for the teensy 4.1 which will need to passthrough the 48 outer teensy pins along with the 6 ethernet pins. I will use two of the 24x1 Sockets on the pjrc store to pass through the teensy pins but I am still searching for which components I should use (pins + socket) for the ethernet. Has anyone made a board in which the teensy is plugged in to a socket which also has a socket for the ethernet pins to be passed through? If anyone has experience or suggestions it would be greatly appreciated!

    I tried this recently, not an ideal solution, but it works mechanically. Haven't ran ethernet thru it yet, that's further down the road.

    The 2mm female sockets are shorter, so I had to use longer male pins. The ones I found were too long, needed to push the plastic down using a press and snipping the excess after soldering.

    I used the following parts to make it work, cutting down the parts and sanding as necessary. It's quite a bit of work to do one board. When it's done, it's a lot of pins to pry apart, so you have to carefully and evenly pull it apart.

    Thanks for the suggestion, this is what I am after for sure. I have not gotten around to making the next revision of my board yet but I will definitely consider these. Since I have posted this I found a few candidates as well.

    I have some good news. Quite some time ago, PJRC ordered a large batch custom length header pins for exactly this use. They finally arrived late last week. I've been reluctant to mention it until now, since I wasn't 100% sure the vendor would really get it right. Fortunately, they're exactly right.

    We're going to sell the pins and socket as a set. I hope to have it on the website soon.

    That's great Paul! I will be sure to use these for my board. Is there a recommended footprint for the header? I'm sure I could use a similar part's footprint and it would be fine but just to be safe. 0.7mm drill / 1.1mm pad?
