Which M.2 wifi card supported?

I'm trying to source a supported wifi card for my ROC-RK3399-PC. I've noticed that the M.2 spot for wifi does not support pcie, but does need a wifi card using SDIO. These seem to be harder to come by, and I'm wondering if anyone can tell what was shipped working or found to work with these. I'm also wondering if this one might work: https://techship.com/products/azurewave-aw-cm389ma/, if anyone knows?

The RTL8723DU is being tuned right now and RTL8822CS is still being developed. The former should be out soon and the latter will require more time. https://github.com/lwfinger/rtl8723du

Any idea where can the hardware be purchased (for either wifi card)? These seem rare enough, if I hadn't seen the photo posted I'd almost doubt their existence.

Renegade Elite is formally launched on July 24th. These are targeted for availability then. The 8723DU uses standard USB connectivity and drivers. The 8822CS uses SDIO which requires significant overlay work. The M.2 E-Key pin out is available on the schematic so any USB based M.2 with matching pin-out (and voltage if it is using other pins besides USB).
