Hello, I am trying to design a HSM4 into my project. I am struggling because the pinout on the DF40C-30DP-0.4V(51) connector is a mirror image of the Zymkey HSM4 cad layout
Do I need to alter the pin assignment on the DF40C-30DP-0.4V(51) connector so that it matches the underside pinout of the HSM4?
Do you have a CAD layout of the HSM to PiZero HAT that I can use as a guide?
Many thanks,
Sam

Yes you will need to alter the pin assignment on the DF40C-30DP-0.4V(51) connector so that it matches the underside pinout of the HSM4. **
See the image below of “HSM PiZeroHat with pin numbers”. More details are available in getting-started-HSM4.
** Zymbit made a call on identifying pin 1, before Hirose documentation was available :(.
Thankyou, that’s really useful. I managed to mirror the layout in the library manager so it matches,
Thanks again,
Sam
