Can also recomment “Sqwincher” (stupid name aside) products.

As they market primarily to people working in construction / other trades - and are therefore sold at the likes of electrical and safety supply stores - we buy them in bulk for when we’re spending weeks installing racks of servers in our datacentre at work.
it’s essentially 2 PCI Express x1 lanes and USB 2.0
Sometimes there’s only a single PCIe lane though. And as you say, that’s not a x2 but explicitly two x1s.
No WiFi card needs the bandwidth (yet), at PCIe 3 speeds you’ve got around 7.8Gbps for a x1, and PCIe 4 double that.
The Coral comes in a “dual” version for exactly this reason (https://coral.ai/products/m2-accelerator-dual-edgetpu/) you just have to be very sure the slot you’re putting it in is actually delivering two PCIe connections.
Also for bonus fun, most WiFi/BT cards use the PCIe interface for the WiFi and USB for the Bluetooth.
My last laptop (owned from 2013-2020) had an NFC reader under the touchpad.
I managed - exactly once - to get my phone to send a file to it using Beam. Did everything exactly as expected; initiated the transfer by NFC and sent the file over Bluetooth.
I could never repeat the experiment. Once, and only once.
While I have a personal general rule against backing electronics on Kickstarter and would likely wait for it to be available at retail, I wouldn’t necessarily immediately discount this one.
It’s probably worth noting - mentioned in Jeff Geerling’s video - they had a MOQ of 1500 on the metal case, which likely forced them to be significantly further through the process than a lot of Kickstarters are at launch.
