Project: The Grand Kiosk, the Seeed Studio ReTerminal DM with Nerves
I’ve mentioned it previously in this thread that I’m poking and playing with the Seeed Studio ReTerminal DM which is a $300-400 piece of industrial kiosk kit. I like the look and feel of it and it makes for a very promising prototype platform for anyone wanting to do visual or interactive stuff with Nerves.
Tom Winkler at Formrausch made a Nerves system for it. And I’m hacking away at a demo-friendly featureful sample project.
Figured I’d show some of my progress here on the forum.
I’ve posted YouTube Shorts about it as well (1, 2, 3).
It comes with a solid set of peripherals:
- Touchscreen
- WiFi antenna
- Light sensor
- Microphone array, two mics
- NervesKey chip (ATECC608)
- Convenient boot switch for flashing the CM4 inside
- Slot for M.2 drive
Plus plenty of ports and some GPIO stuff. It can also be enclosed to make it reasonably IP-classed for water and dust supposedly 
A variant exists that gives you PoE + a camera. Wish I’d grabbed that, it is not upgradable to it.
I will try to put notes about what I do with this thing as I go Feel free to ask questions if you follow along.

I did get the necesseray VAD bits working outside of Nerves and documented it:
I am a bit stuck on a cross-compilation issue for Ortex that I’m not Rust-qualified to figure out. Seems like something generates a crap flag further down. I don’t think I even need the HTTP client that the failing TLS dependency uses.
So close

I popped the ReTerminal open to look into this:
You can actually use the AI Kit with a Pi CM4 if you have a board that breaks out PCIe. The ReTerminal DM does do that. But neither the AI Kit or my PCIe to M.2 adapter would fit. So I should probably have ordered it with the NVMe expansion board or something.
