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.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?

Definitely curious. If works let me know I will order a eval boardI drafted a quick PCB layout to connect the 1XK eval board to Teensy 4.1.
Hopefully both will arrive by next week.
This is looking promising, good work!I drafted a quick PCB layout to connect the 1XK eval board to Teensy 4.1.

I noticed the '32Khz' on the silkscreen,
Today I discovered ublox also makes a module with the same IW416 chip Murata 1XK, and they also sell it on a M.2 module. Digikey has them in stock. Looks like the same pinout, so likely to also work (assuming I can get the software going). Part number is M2-MAYA-W161-10C.
1.4 Software
A detailed description of the wireless interface drivers and configuration instructions for a Linux host
computer are included in the system integration manual for each module type. [7], [8], [9]
The documentation for NXP software releases includes Wi-Fi and Bluetooth release notes and a list
of supported software features. The driver source code is provided free of charge as open source
under NXP license terms. As an open-source resource, the drivers may be integrated or ported to other
non-NXP based host platforms. Yocto recipes for the driver and firmware, that can be used to develop
custom Linux-based systems, are part of the NXP i.MX Linux BSP in the meta-imx and meta-freescale
layers.
The latest version of the driver source code and Wi-Fi/Bluetooth firmware are available from the
following open-source repositories:
• Wi-Fi driver: https://github.com/nxp-imx/mwifiex
• Firmware: https://github.com/NXP/imx-firmware
☞ Use the repository branches matching to the latest Linux BSP release version. At the time of
publication, this is release 6.6.23_2.2.0.
The configuration guide for NXP-based Wireless Modules [15] provides a useful reference for
configuring and using the Wi-Fi and Bluetooth features for NXP-based wireless modules. The
supported Wi-Fi features described in the guide include scanning for nearby access points,
connecting to an access point, configuring the device as an access point, Wi-Fi security, Wi-Fi Direct,
and throughput testing using the iperf3 utility. The described Bluetooth features include scan, pair,
connect to a Bluetooth or Bluetooth Low Energy (LE) device, A2DP profile, handsfree profile and
Bluetooth LE device as a GATT server. Guidelines for enabling driver debug logging are also provided.
Good luck!!Now I have a lot of software experimenting to do.
Hopefully the only error!M.2 standoff misplaced a bit
Yes antenna is optional.Hopefully the only error!
Are Antennas optional ? - nice how they don't waste ink and add silkscreen for Bt .vs. WiFi.
Good to check as some radios with no antenna die on Tx. I assume the 'lower' is WiFi and it looks like a PCB antenna - and maybe removing that component by the plug activates the plugged antenna, but the upper plug doesn't seem to have that for Bt - unless it is underneath or the freq works otherwise without a big obvious topside PCB layer?Yes antenna is optional.
