Access Reader Design
Worked for 1 min 27 sec
Текущий 80×100 мм layout всё ещё физически перегружен и даже однослойный targeted router блокируется; для order-ready в пределах вашего лимита увеличиваю плату до 120×100 мм и повторяю edge-placement/stackup.
Thought for 12 sec
В этом запуске я успел перечитать live layout/DRC/stackup: плата сейчас 80×100 мм, сильно перегружена, часть компонентов/отверстий выходит за габарит, DRC всё ещё показывает сотни airwires, а stackup readback остаётся некорректным — фактически внутренние GND/PWR слои не подтверждены как рабочие.
Что осталось сделать:
- Пополнить ACUs — сейчас AI-функции недоступны, поэтому я не могу продолжать tool execution.
- Увеличить плату до 120×100 мм в пределах вашего лимита.
- Повторить placement: все разъёмы/клеммники на кромки наружу, 4 отверстия Ø3.2 по углам, antenna keepout у края.
- Исправить/подтвердить stackup Top / Inner1 GND / Inner2 PWR / Bottom.
- Завершить routing, убрать все airwires, пройти DRC.
- Только после чистого DRC экспортировать order-ready Gerber+drill, BOM с DNP-колонками и Pick-and-Place.
Текущий пакет не order-ready.

Rev A Implementation Plan - Access Reader
Purpose
This plan converts the uploaded technical design and pre-review findings into the next engineering actions for schematic Rev A.
Decision
Proceed with a full first Rev A prototype on one PCB: populate both PoE/Ethernet and 9-32 V DC/Wi-Fi paths. The first schematic pass must lock core components, GPIO allocation, safe 5 V OR-ing, power architecture and external protection before detailed RF tuning or final layout.
Stage 0 - Close Pre-Schematic Gates
Table
| Gate | Output | Status |
|---|---|---|
| GPIO allocation | ESP32-S3 pin table with boot states and reset defaults | Open |
| Power budget | Datasheet-backed rail currents and PoE class | Draft estimate exists |
| Population matrix | Full prototype population and no-backfeed scheme | Updated: PoE/W5500/RJ45 and DC buck all populated |
| RF floorplan | Wi-Fi/NFC/LF/QR physical zones and keepouts | Open |
| Protection matrix | Per-port ESD/EFT/surge circuits | Draft exists |
| Memory plan | ESP-IDF partition and wear plan | Open |
Stage 1 - Add Main Schematic Blocks
Add only main components first, then wire support circuits after datasheet checks.
-
Core MCU and service interface
- ESP32-S3-WROOM-1-N16R2
- BOOT/RESET, native USB service, test pads
- Secure production/debug assumptions
-
Power entry and rails
- 9 to 32 V protected DC input and LMR16020 5 V buck
- AG9905-MTB 802.3af PoE module path
- Reverse-blocking ideal-diode OR / priority power mux into
5V_SYS - Common 5 V and 3.3 V regulators, power-good/reset
-
Communications
- W5500 Ethernet populated in first prototype
- RS-485 transceiver
- Wiegand output drivers
-
Credential readers
- GM861 QR connector and power switch
- CLRC663 plus NFC front-end with matching placeholders
- EM4095 LF front-end with coil connector/tuning placeholders
-
Access I/O and UI
- Two relay drivers and Form C terminal blocks
- Two isolated inputs and tamper
- WS2812B/status indication and buzzer
- RTC PCF8563 and backup battery
Stage 2 - Datasheet-Backed Support Circuits
For each IC, verify and add:
- Required decoupling and bulk capacitors.
- Pull-ups/pull-downs, boot straps and reset networks.
- Recommended regulator compensation/inductor/capacitor values.
- Interface protection and termination.
- RF matching/tuning placeholders and test pads.
Stage 3 - Schematic Verification
- Run ERC/design review.
- Check all power pins, grounds, no-connects and support passives.
- Check external-port voltage tolerance and protection.
- Verify relay default-off state and Wiegand default-high/open state.
- Verify ESP32 boot and USB download path.
Stage 4 - Layout Checkpoint
Pause before PCB layout routing. Required before layout starts:
- Board/enclosure size or at least antenna/mechanical zones.
- ESP32 antenna edge placement and keepout.
- NFC/LF antenna dimensions and test strategy.
- PoE isolation boundary and creepage rules.
- Connector side/orientation and mounting plan.
Recommended Immediate Next Action
Start with component sourcing and datasheet verification for the core blocks: ESP32-S3-WROOM-1-N16R2, GM861 connector/module data, CLRC663 plus, EM4095, W5500, TPS54360B, PoE PD/flyback option, 3.3 V buck, relays and external protection devices. Then add the main components to the schematic block by block.
