High-Level Block Diagram Creation

R

rodgerliu

Create a high level mermaid block diagram of this project. Include key component's manufacturer part number in each block whenever possible.

I’ll inspect the project structure and BOM, then create a concise high-level Mermaid block diagram document with MPNs where available.

I found the major blocks: RP2350 MCU, power tree, M40 interface, XY2/encoder DB25, laser safety, I2C expanders, isolated digital I/O, and analog ADS8688-LZM8688 interface. I’m saving the diagram as a project document now.

Created the high-level Mermaid block diagram and saved it in High Level Block Diagram. It includes the main functional blocks and key MPNs from the schematic/BOM, with caveats for connector-only or ambiguous regulator entries.

当前限制/待补齐
  • Flux当前可用工具未提供原生Sheet页面创建/层次端口图形化编辑接口；已用Section属性和命名网络记录Sheet归属。
  • DB25、DB9、26Pin、J6、J_M40、J_IO、J_OMx等多针连接器精确库符号仍需导入或创建后才能完成所有CONNECT语句。
  • LZM8688库件未找到，未创建错误占位符；Sheet 9需导入该模块符号后补齐。
  • ERC会存在Floating Pin，属于未完成连接器/CONNECT补齐阶段的预期结果。
