Project Started
Worked for 3 mins 14 sec
Revised the design around a TCA8418 keypad scanner: all 20 diodes were removed, the 5×4 matrix now connects only to the scanner, and I²C, INT, RESET, decoupling, and required pull-ups were added. The potentiometer and latching-switch sections remain intact; ERC and legibility checks are clean.

The project specification, firmware guide, and bring-up plan were also updated for the TCA8418 architecture. The next priority is reviewing the schematic before starting PCB placement.
Start Auto-Layout
Thought for 10 sec
I’ll inspect the board state first, determine whether placement, routing, or both are incomplete, then run the required auto-layout steps and validate the applied result.
Worked for 2 mins 44 sec
Placement was required—the prior components were mostly off-board—and is now applied as a 5×4 key grid with grouped scanner, controls, and MCU. The board passed routing preflight, so full trace routing is now running.
Worked for 6 mins 27 sec
Both placement and routing were needed.
- Re-placed all 44 components inside the 160 × 100 mm, 4-layer board.
- Arranged the 20 keys into a 5×4 grid and grouped the TCA8418, ESP32-S3, analog controls, latching switches, and support passives.
- Cleared placement overlaps and out-of-bounds errors in the placement validation.
- Generated 23 fine-pitch neckdowns for the TCA8418.
- Routing preflight passed with only an informational via-at-SMD adjustment for the TCA8418 exposed pad.
- Started auto-routing; the partially applied result currently has approximately 126 airwires remaining.
Routing is not complete. The existing auto-route job is paused and can be resumed without discarding its progress. Execution stopped because your ACUs ran out.
