Schematic Block Reorganization


I’ll reorganize the schematic into clear functional blocks, add concise block titles/descriptions, then inspect connectivity and readability to ensure the electrical design is unchanged.
Assigned all 59 physical components to seven functional groups: USB-C input, battery charging/power path, 3.3 V buck, 5 V boost, ESP32-S3 controller, USB-A interface, and bring-up/mechanical. Connectivity is unchanged, and verification found no open ERC or schematic-legibility errors.

  • Actual symbol rearrangement and visible block-description text could not be added because schematic canvas placement/annotation editing is unavailable in the current toolset. The functional groups are present, but the visual layout remains unchanged.
Use Schematic Arrange to visually group the blocks, then add the descriptions to a project doc.
I’ll use Schematic Arrange to cluster the seven existing functional groups, then create a concise project document describing each block and verify the resulting schematic legibility.

Created Schematic Functional Blocks with descriptions of all seven blocks and their inter-block signal/power flow. Connectivity and ERC remain clean, but visual rearrangement is blocked because Schematic Arrange is unavailable in this tool session; no schematic or PCB geometry was changed.
