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.
Open item
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.
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.
All 59 physical components placed on the top layer.
USB-C J1 is on the left short edge; USB-A J2 is on the right short edge; J3 battery connector is on the bottom edge.
ESP32-S3 module U1 is placed at the top edge with the antenna extending beyond the board boundary.
Power sections are grouped: BQ24074 charger near USB-C/battery, TPS62840 buck near its passives, TPS61023 boost near its passives.
Test points are placed in an accessible row.
Verification findings
Layout is physically configured and placed, but the ESP32 antenna overhang makes the aggregate component bounding box extend beyond the board in Y. This is intentional for antenna performance, but the exact keepout region should be manually reviewed before fabrication.
Airwires remain because routing has not been completed. Manufacturing files should not be generated until routing is finished and review is clean.
The schematic contains several unresolved functional issues that should be corrected before final PCB routing:
