PCB Design Progress Update
Worked for 15 mins 6 sec
I’m blocked because there are no available ACUs, so I can’t continue routing or final verification.
Accomplished this session:
- Read the new attachment and kept the corrected 100 mm × 70 mm, 2-layer board.
- Verified the AP63203 power circuit and fixed the blocker:
- C6 is now between BST_3V3 and SW_3V3.
- SW connects to U2 SW, C6 P2, and L1 P1.
- FB remains connected to 3V3 after L1.
- VIN/EN remain tied to 5V.
- Moved C6/C7 and the buck support parts back onto the PCB in a compact cluster.
- Cleared the autorouter precheck blockers from overlapping pins and antenna-keepout intrusions.
- Confirmed the autorouter precheck reported the board valid before routing.
Open items:
- Autorouting did not complete because ACUs ran out.
- The autorouter also reported one placement anomaly: “Board fully placed. Move components to be placed outside the boundary.”
- Final ERC/DRC/airwire checks are still not complete.
- Manufacturing review/BOM/footprint caveats still need updating.
Suggested next steps:
- Add ACUs, then rerun autoroute from the current state.
- If the placement anomaly persists, slightly relax/spread the dense ESP32/TFT/encoder region without changing the 100 mm × 70 mm board.
- Run ERC/DRC/airwire checks and fix remaining issues.
- Update the manufacturing review and explicitly list footprints requiring physical verification.

- BOOT button GPIO0.
Manufacturing cautions
The USB-C connector footprint and EC11 encoder footprint must be verified against the exact purchased parts before ordering boards. Any generic or approximate footprint must be marked as temporary until checked against a datasheet or measured sample.
