A comment on I learned PCB design, 3D printing and C just to listen to music.

This is really cool. I would love to switch from using the SoM I'm currently using to the Radxa CM3 but I cannot find even a single unit actually available for purchase on any of the "international" distributor options.

Can you speak to how you're sourcing these, and from where? (And would you sell me one?)

I buy them on AliExpress.

Every variant comes up as not available.

This is the listing, right?

Yes, this was it, looks like it is gone now. According to the CM3 datasheet [0] "Radxa CM3 will remain in production until at least Sep 2029", so there should be inventory hopefully.

I've been talking to them since before my first comment to you, and they are unable to sell even a single unit to a verified engineering team.

They told me that if I am willing to commit to at least 300 of the 4GB/32GB eMMC + BT/Wifi then they could produce them for me on demand.

I told them that it was insane to expect anyone to commit to developing a product around a platform that they would have to buy USD$30k worth of to see if it could (for example) support a particular display panel configuration using eDP.

Having this kind of chicken-and-egg problem is a quick way to doom a SoC, which is super frustrating because I definitely want to use it.
