I'm trying to draw a new board for hobby project that utilize the CM4 (Compute Module 4). However, I didn't found any footprint for the connector module of the board to board connector between CM4 and the IO board in KiCAD.

Any one knows what is the module, or where can I found the library that contains the module for KiCAD? Or any one has experience of where to look for such information?

For the IO board

The connectors are made by HiRose.

There are two types for the IO board, varying in height: 1.5 mm and 3.0 mm.

From page 16 of the CM4 data sheet:

a. 1.5mm with mating connector (clearance under CM4 0mm) : DF40C-100DS-0.4v

b. 3.0mm with mating connector (clearance under CM4 1.5mm): DF40HC(3.0)-100DS-0.4v

On Digikey:

For the CM4 module

Note that the CM4 board itself has the "male" DP variant, not the "female" DS, so if you are looking to replace broken connectors on a CM4 board (as I am), then you need
