High-Level Block Diagram Creation
Create a high level mermaid block diagram of this project. Include key component's manufacturer part number in each block whenever possible.
Thought for 4 sec
I’ll inspect the project structure and BOM, then create a concise high-level Mermaid block diagram document with MPNs where available.
Thought for 1 min 27 sec
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.
Worked for 23 sec
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.
Review diagram and ERC
Run schematic ERC
Fix ambiguous MPNs
Create power tree
Check BOM risk

M40连接器确认
- 使用ADAM Tech CFA-50-A-SG-1。
- Pitch：1.27mm。
- 不使用HMS SP1137-2作为BOM连接器。
- 当前用J_M40_A + J_M40_B作为50Pin Schematic等效表达。
ERC最终结果
- 最终ERC检查项：Floating Pin、Single Pin Net、Undriven Net、Missing Power、No Connect、Pin-to-Pin、Driver Conflict、Shorted Components。
- 当前结果：未返回ERROR/WARNING/OPEN项。
重要说明
- Flux当前工程中使用大量Net Portal表达跨页/层次连接，这是Schematic对象，不是PCB图。
- 目前没有执行任何PCB布局相关操作。
- 若后续进入Layout阶段，需要重新进行真实器件封装、板框、布局、布线和DRC；当前报告只覆盖Schematic/ERC。
待后续工程复核
- LM5013的RON/FB/BST/SW等网络已建立，但仍建议按datasheet复核精确阻值、频率和启动条件。
- RP2350B VREG/DVDD网络已命名，建议后续按Raspberry Pi参考设计复核旁路与电感/电容。
- LZM8688当前用接口连接器表达模块，而非完整自定义模块符号。
