Would the HA Yellow support a CM5, which was just released?
According to https://www.raspberrypi.com/documentation/computers/compute-module.html it says to have the same formfactor as a CM4 with the same 100-pin connector - ?
Ah no - don’t think so: https://www.raspberrypi.com/news/compute-module-5-on-sale-now/. It says there:
Compute Module 5 is mechanically compatible with its predecessor, Compute Module 4, exposing all signals through a pair of high-density perpendicular connectors, which attach to corresponding parts on the customer’s carrier board. Additional stability is provided by four M2.5 mounting holes arranged at the corners of the board.
There are a small number of changes to the pin-out and electrical behaviour of the module, mostly associated with the removal of the two two-lane MIPI interfaces, and the addition of two USB 3.0 interfaces. A detailed summary of these changes can be found in the Compute Module 5 datasheet.
“Appendix C: Differences between CM4 and CM5” provides more details from the above referenced PDF.
