Product Introduction
The X3568V4 mainboard is based on the Rockchip RK3568 / RK3568B2 platform and uses the X3568CV2 / X3568CV3 core board. RK3568 integrates a quad-core ARM Cortex-A55 CPU running up to 2GHz, and is suitable for intelligent terminals, industrial control, display control, multimedia devices, and embedded system development.
The X3568 core board has two versions: X3568CV2 uses DDR4 memory, while X3568CV3 uses LPDDR4 / LPDDR4X memory. The two versions are pin-compatible and software-compatible. The RK3568 chip is available in metal-lid and plastic packages; the latest 9Tripod code can support both packages.
