Most ChromeOS devices are designed for either the consumer or educational markets, but Google’s operating system can also be used for commercial applications such as digital signage.
A cheap way to set up a ChromeOS based digital is to get a ChromeBit (around $100 used) and install one of the Digital Signage apps for the OS. But as I checked out Linux 5.4 changelog, I came across AOPEN Chromebox Mini (codename Fievel) powered by a Rockchip RK3288 processor and described as an “enterprise-ready” Chromebox for 24/7 operation as digital signage or kiosk.

It’s sold on Amazon for around $260, and there are mixed reviews mostly from people bought it as a mini PC, si as the processor is quite slow for a typical end-user, but this should not be an issue for digital signage.
More details may be found on the product page. If you’d prefer something a bit more recent and powerful, the company introduced Chromebox Commercial 2 with a similar form factor, support for dual 4K output, and a choice of Intel Celeron 3865U or Core i3-8130u processor for respectively $363 and $683.
