YKR-CR3399-V1 core board is designed based on Rockchip's RK3399K processor. It contains 2 ARM Cortex-A72 cores with a main frequency of 1.8GHz and 4 ARM Cortex-A53 cores with a main frequency of 1.4GHz. The GPU uses Mali-T864 and supports OpenGL ES 1.1/2.0/3.0/3.1, OpenVG 1.1, OpenCL and DX11. It has 2GB LPDDR3 RAM and 16GB eMMC ROM on board. The core board has multiple display interfaces, including HDMI 2.0, MIPI-DSI, eDP 1.3 and DP 1.2, with a maximum resolution of up to 4K, and supports dual-screen same display and dual-screen different display. At the same time, the core board also provides a variety of peripheral interfaces, such as PCIe, USB3.0 Host, Type-C, MIPI-CSI, SPDIF, I2C, SPI, UART, ADC, PWM, GPIO and I2S (supporting 8-channel digital microphone array input), as well as Gigabit Ethernet.
