Yup. The daughterboard is on my mind. Likely flex-PCB and that’s gonna take a week or two to respin. Hence I’m collecting ideas for various daughtercards I could cram in a panel before sending it off - straight-through to riser via USB3, expresscard SMT, maybe through-hole 1x?
That said, PCIe phy’s are extremely robust - they do most of the impedance matching and delay mismatch training. And if you don’t ruin the onboard caps, this could be jumpered straight across.
- segfaultbuserr 7y agoGreat! I was thinking about using a SMT ribbon cable connector because of the limited available space, but apparently it won't be an issue if you raise the board high enough? Anyway, if this project ever goes to batch-production, make sure to update your blog when the funding campaign starts!
