Mekotronics has introduced the R57-5S, a compact embedded computer built around the Rockchip RK3576 SoC and aimed squarely at kiosk and digital signage deployments. The defining feature is an inclined 5-inch touchscreen display built directly into the aluminum chassis, measuring 162 x 111 x 46 mm, giving operators a local control interface while driving one or two larger external displays simultaneously.
The RK3576 inside pairs four Cortex-A72 cores at 2.2GHz with four Cortex-A53 cores at 1.8GHz, a Mali-G52 MC3 GPU with Vulkan 1.1 support, and a 6 TOPS NPU for on-device AI inferencing. The system supports up to 16GB LPDDR5 memory alongside up to 128GB eMMC or up to 1TB UFS flash, and an M.2 M-Key slot accepts either NVMe storage or an external AI accelerator module. Video output covers HDMI 2.1 (up to 8K at 30fps) and USB-C DisplayPort 1.4, while a dedicated HDMI input handles capture up to 4K at 60fps, a useful addition for signage systems that need to relay or process an incoming video feed.
Connectivity includes dual Gigabit Ethernet, WiFi 5, Bluetooth 5.1, and an optional 4G LTE and GPS module via a mini PCIe slot. A terminal block exposes RS232, RS485, and GPIO interfaces for integration with industrial peripherals. Supported operating systems include Android 14, Buildroot, Debian, and Armbian, and the Linux foundation underneath is increasingly solid: Collabora merged H.264 and HEVC hardware decode support for the RK3576 into the mainline Linux kernel as of Linux 7.0, with GStreamer 1.28 already incorporating the accompanying V4L2 controls. Community members have also been active in Armbian's forums around the R57 hardware family, with alpha images running kernel 6.15 and Panfrost-accelerated graphics documented on both Wayland and X11. The R57-5S product page lists a starting price of $260 (€240) for the 4GB RAM and 32GB eMMC configuration, with pricing described as negotiable for volume orders.
