Are the JMISC and JMEDIA high speed headers designed as a new standard to be used with upcoming boards as well, or are they just conveniently routing out what is specifically available on the QRB2210/STM32U5 of the board. And future boards will not be compatible/provide peripherals via the same connector positions.
Thanks!
I'd love to know the part number for a matching plug for these connectors. I see it's 1.27mm pitch?
@stratom position will stay the same, the signals available be adapted following the features of the MPU / MCU
common signals will be typically available in the same position (like the headers on the TOP )
@manekij here you go.
Male connector: samtec FTSH-130-01-L-DV-P-FR
Female connector: Samtec FLE-130-01-G-DV-K-FR
can’t wait to see new carriers

Where can I find a drawing with connector locations?
You can download .stp files from the downloadable resources at https://docs.arduino.cc/hardware/uno-q/
There is also useful information on the new Arduino Uno Breakout Carrier Datasheet.
Here are two drawings from that datasheet:
