Serial Port Expansion Card

As someone who works in an industry that requires serial connection occasionally to configure switches and various lab hardware. It would be great to have a serial expansion slot.

I don’t even have a framework laptop yet because I am waiting for the 16. But being able to have a serial port would be a nice little feature to have for my daily work. I did some research and couldn’t find any so if someone knows of one I can save for future use that would be great!


Welcome to the forum.

Do you mean with a DB9 Connector? Because I don’t believe that would fit on an expansion card.

If you don’t need the DB9 connector, then

I did mean the DB9 connector. Hmmm maybe whenever I get a laptop I will have to look closer at it and see if it would fit or not. Thanks for the help.

One can easily be made from the myriad of serial adapters out there.


I haven’t quite finished this, the socket needs soldering to the board and LEDs added.

Something like this.


@Moe_Wigs what usb c board did you use for that?

It’s a DSD TECH SH-U09B3.

Thank you! Do you have a cad model for the enclosure as well?
