# Pinouts # 引脚定义
All pin definitions for LattePanda Mu LattePanda Mu 全部引脚定义
⚠️ Note: ⚠️ 注意:
Due to the large number of functionally multiplexing pins, you should check the [BIOS functionality documentation](../../Softwares/BIOS/README.md) before starting your design. Do not design directly from the pin definition documentation here. 由于存在大量功能复用引脚，因此在开始设计前请先查看 [BIOS 功能文档](../../Softwares/BIOS/README.md)。请勿直接根据此处的引脚定义文档进行设计。
