1.1 Overview
The YF-055E board adopts the Rockchip RK3568 high-performance, low-power quad-core application processor with Android 11.0 OS and a main frequency up to 2.0 GHz. The embedded 3D GPU enables full compatibility with OpenGL ES 1.1/2.0/3.2, OpenCL 2.0, and Vulkan 1.1. A dedicated 2D hardware engine maximizes display performance and ensures smooth operation.The built-in NPU supports 1.0 TOPS. It supports nearly all video formats: H.264 decoder 4K@60fps, H.265 decoder 4K@60fps, H.264/H.265 encoder 1080p@60fps, and high-quality JPEG encoder/decoder.Integrated with multi-channel LCD drivers, Ethernet, dual-band Wi-Fi/BT power amplifier, it supports decoding of most popular video and image formats. Dual LVDS/EDP/MIPI supports 2K-level output, compatible with various TFT LCD panels, simplifying overall system design.

Chapter 5 Assembly and Usage Notes
During assembly and use, pay attention to the following (but not limited to):
1. Short‑circuit risk between bare board and peripherals.
2. Avoid PCB deformation during installation/fixing.
3. When installing EDP/LVDS panels, verify voltage/current and pin 1 orientation.
4. Check backlight voltage/current; if backlight power >20W, use an external power supply.
5. Verify peripheral I/O levels and current ratings.
6. For serial ports, confirm TX/RX wiring if connecting to RS232/485 devices.
7. Connect power to the dedicated input connector only. Do not power via backlight header.
