RPi do name the connector in the CM4 datasheet: https://datasheets.raspberrypi.org/cm4/cm4-datasheet.pdf https://datasheets.raspberrypi.org/cm4/cm4-datasheet.pdf You can buy the connector here: https://uk.rs-online.com/web/p/products/1362374/?grossPrice=Y&cm_mmc=UK-PPC-DS3A-_-google-_-3_UK_EN_PCB+Sockets_Hirose_Exact-_-Hirose+-+PCB+Sockets+-+1362374+--_-df40hc+3.0+100ds+0.4v+58&matchtype=e&kwd-360440442175&s_kwcid=AL!7457!3!443699393884!e!!g!!df40hc%203.0%20100ds%200.4v%2058&gclid=CjwKCAiA-f78BRBbEiwATKRRBC8Esi76AkQ1bSJYGLpJxmm5f_Dx4wXqlh1E3D5V0HGgEUkYMGRvpBoCiHEQAvD_BwE&gclsrc=aw.ds https://uk.rs-online.com/web/p/products/1362374/?grossPrice=... I agree with you though. RPi appeals to people with a wide range of skills. There are lots of programmers who want to use Pi to get more electronics knowledge, and RPi foundation could make that a bit easier for those people. (EDIT: I don't understand why parent has been downvoted. A lot of similar devices do use newer more specialised connectors and it can be hard to work out who makes and supplies the connectors.)
