OpenWrt One and its mikroBUS

The One is a nice little unit and I've got mine up and running using rc5. I'm very impressed with it. The range of packages available and the addition of the nvme slot makes it very easy to setup and manage.

I'm now wondering if the mikroBUS support is doable, and what level of expertize is required to make that happen.

I see that @markbirss has had success with a loRa unit and Meshtastic. Obviously with a lot of development work. Sadly I have no use for a LoRa network although the concept is great, I'm in a remote location and finding someone to connect to would be a lonely search.

Adding a 3rd RJ45 device could be an option. With the intention of replicating an old school physical DMZ zone, rather than a VLAn style one.
To that end, these ETH Click devices may be suitable but I'm currently out of my depth here.

They have quite a few interesting modules on that page, 1-wire, GPS, etc. It looks like a whole other world awaits with the SPI; If the tools or skill set matches.

My skill set would be on the low end, If I need to bootstrap it then there won't be a day wet enough for it to happen, but ?? ... I've go to ask to know what lies ahead.

Any clarifying comments would be appreciated.

While that may be possible for the M.2/ PCIe slot, it's not a use case for mikrobus. Mikrobus covers i2c/ spi lanes, these are not particularly high-speed busses and way too slow for ethernet.

(the sensible solution would be getting a decent (second hand?) managed switch instead).

There is a u-tube video https://www.youtube.com/watch?v=I0n53oVkQns that details adding another 2.5GbE to the OpenWrt One using the PCIe to 2.5GbE NIC with Intel I225-V Controller, but it's less than a pretty installation. I agree with @slh on the Sensible Solution.
