@tltangliang The WisdPi board you mentioned doesn’t seem to be listed on their website anymore - your link (WisdPi - Focused on wisd hardware development.) seems to just go to their homepage now, and it’s not listed under Products?
Also - the converters mentioned above all assume you have either USB 4.0, or a Thunderbolt 3 or 4 port available.
However, what about if you have only USB 3.x ports available?
In this other post, they mention a Graugear M2. Enclosure, which uses a RTL9210B-CG bridge chipset.
Can I just confirm that this sort of enclosure would work with the Hailo-8/8L, to convert the native PCIe interface over to USB 3.0?
