The 3.5″ SBC-R39 of Kontron is a compact 3.5″ single-board computer for high-performance and low-power systems. It is built on a Rockchip RK3399(K) processor with ARM big.Little microarchitecture. This includes two processors embedded in a single, fully integrated silicon chip. The Little cluster consists of a quad-core Cortex A53 processor, which is typically used to perform routine tasks at low power consumption. The large cluster is a dual-core Cortex-A72 processor, which handles compute-intensive high-performance tasks. With the high-end Mali-T864 GPU from ARM integrated into the processor, the SBC enables high-performance 4K UHD video decoding and 4K UHD video playback at up to 60fps via DisplayPort and HDMI 2.0 connectors.
