We already have available in stores the latest Android Box for digital signage from RKM, its RKM DS03 that includes a hardware design and specific functions for advertising applications.
A Box that includes a metal case to promote cooling and this time includes the powerful Rockchip RK3399 SoC that we have already seen in many development boards. Its firmware has options such as screen rotation and automatic power off/on, which are widely used in digital signage, and inside we find connectors for LVDS, touch screen, microphone and others. We also have the option to buy it with a 4G-LTE modem that allows you not to depend on Wifi networks, like the RKM DS02 that we saw some time ago in one of our reviews.
