In addition to Arduino Giga, I ordered a couple of this eval board with the 1XK module. Will make a M.2 adaptor PCB soon...
1XK is more expensive, but it's dual band. Most routers have 5 GHz Wifi and many upstream internet connections are usually fast enough to support it, so perhaps the more expensive 1XK will be worth its extra cost?

We should absolutely get the 1XK to work as well. I'm all for that. Will let you know the second the 1DX's and 1YN's ship from factorym should be in a few days.

I drafted a quick PCB layout to connect the 1XK eval board to Teensy 4.1.
Hopefully both will arrive by next week.
If anyone's curious, here's my notes about the connections.

Definitely curious. If works let me know I will order a eval board

This is looking promising, good work!

I started a deep dive into the Linux kernel source, since there just doesn't seem to be any 1XK programming documentation. Haven't gone very far yet, but I'm pretty sure this struct is the device info and this other struct is probably the actual hardware registers. Will post updates as I learn more...

Turns out the circuit boards (msg #29) that I ordered from China on July 3 will arrive today (Monday), but the 1XK eval boards I ordered from Texas on July 2 won't come until Wednesday. Also due to arrive Wednesday are the 1DX and 1YN boards from @Dogbone06. I'm excited to really get into the software, but looks like I need to wait a few more days to have enough hardware to even start.
