Access Reader Design

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.
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.

Access Reader Manufacturing Status
Current Status
Updated 2026-07-09 after critical correction: first Rev A prototype is FULLY POPULATED with both power inputs and both network paths.
Confirmed Design Direction
  • Populate PoE 802.3af path: AG9905-MTB + RJ45 MagJack + W5500 Ethernet.
  • Populate DC path: 9-32 V input + LMR16020 5 V buck.
  • Populate Wi-Fi: ESP32-S3-WROOM-1-N16R2 remains the wireless path.
  • Do not mark PoE, W5500 or RJ45 as DNP for the first prototype.
  • Do not directly parallel PoE 5 V and DC buck 5 V outputs.
  • Merge 5V_POE_PRE_OR and 5V_DC_PRE_OR through reverse-blocking ideal-diode OR / priority power mux into 5V_SYS.
Antennas, Mounting and Board Envelope Update — 2026-07-09
  • Board size target remains 80 × 100 mm because compact Rev A is preferred.
  • Board may grow only if antenna/keepout/mounting clearance physically requires it; hard maximum is 120 × 100 mm. Do not enlarge without necessity.
  • Hard connector placement constraint: all cable connectors and terminal blocks must be on PCB edges with the mating/opening/cable-entry side facing outward and with unobstructed insertion clearance outside the board outline. Inward-facing or mid-board connector access is a manufacturing defect. This applies to RJ45/MagJack Ethernet, 9–32 V DC input, both relay NO/NC/COM terminal blocks, service USB, RS-485, Wiegand, two input connectors, GM861 QR connector/FPC/header, and J101 125 kHz coil connector.
  • The RFID/card-presentation antenna edge must remain a free presentation edge without unrelated connectors; only antenna/coil-related geometry such as J101 may be adjacent where it supports the LF antenna approach zone.
  • Existing project already had RFID front-end ICs: U13 CLRC663 for 13.56 MHz and U14 EM4095 for 125 kHz. No existing PCB NFC loop, CLRC663 antenna matching/EMC chain, external LF coil connector, LF tuning capacitors, or standalone board mounting holes were confirmed before this update.
  • Added schematic components for four board mounting holes: H1–H4, M3 / Ø3.2 mm intent, excluded from BOM and pick-and-place. Intended placement on 80 × 100 mm board: centers at approximately ±35 mm X and ±45 mm Y, giving ~5 mm edge inset; reserve ≥6 mm copper/component keepout around each.
  • Added U8 as the on-board 13.56 MHz printed loop antenna. Requested designator ANT1 was unavailable and Flux assigned U8. Library footprint intent is ~40 × 40 mm PCB loop; all copper/power/GND pours must be kept out under the antenna on every layer.
  • Added CLRC663 tune/EMC placeholders: R101/R102 series Rq placeholders, C101/C102 shunt EMC placeholders, C103/C104 matching/sense placeholders. Values are EVT tuning placeholders / DNP unless tuned after antenna measurement.
  • Added LF 125 kHz external coil interface: J101 2-pin connector for external coil, C111 resonant capacitor placeholder across ANT1/ANT2, and C112 EM4095 FCAP/tuning placeholder. The external coil is expected to be hundreds of µH and tuned at EVT.
  • Schematic nets added/verified: CLRC663_TX1_RAW, CLRC663_TX2_RAW, NFC_ANT_A_MATCH, NFC_ANT_A, NFC_ANT_B_MATCH, CLRC663_RXP_SENSE, LF_125K_ANT1, LF_125K_ANT2, EM4095_FCAP_TUNE.
  • PCB layout execution note: layout/board mutation tools repeatedly returned missing project-context errors during this update, so the schematic/RF BOM placeholders were committed, but board outline/placement/keepout geometry must be verified/applied in the next successful PCB layout pass.

Manual Connectivity Checklist for Schematic Completion
  • AG9905_5V_OUT -> OR-ing input A -> 5V_SYS.
  • LMR16020_5V_OUT -> OR-ing input B -> 5V_SYS.
  • No direct net tie between AG9905 output and LMR16020 output before OR-ing.
  • 5V_SYS feeds 3.3 V buck, 5 V loads, local bulk capacitors and test point.
  • 3V3_SYS feeds ESP32-S3, W5500, CLRC663, RS-485/RTC/logic and test point.
  • W5500 SPI shares SCK/MOSI/MISO with CLRC663 but has separate CS/INT/RST.
  • RJ45 MagJack is connected both to W5500 Ethernet pairs and AG9905 PoE input as required by the selected module/reference circuit.
  • ESP32 boot pins GPIO0/GPIO3/GPIO45/GPIO46 remain boot-safe.
pcbfast Fabrication Target
  • Layer count: 4 layers recommended because Ethernet/USB/SPI/Wi-Fi coexist; 2-layer is not recommended for this Rev A unless complexity is reduced.
  • Stackup intent: Top signal/components, Inner1 solid GND, Inner2 power, Bottom signal.
  • Minimum trace/space: 6 mil / 6 mil.
  • Minimum drill: 0.3 mm.
  • Finish: ENIG.
  • Add controlled return paths for USB and Ethernet; keep ESP32 antenna at board edge with all-layer antenna keepout.
  • Board envelope: keep 80 × 100 mm if feasible; absolute maximum 120 × 100 mm.
  • Mounting holes: four M3 / Ø3.2 mm holes, ~5 mm center inset from board edges, with ≥6 mm copper/component keepout.
  • RFID antenna zones: 13.56 MHz printed loop and 125 kHz external-coil connector/keepout must be at the card presentation edge, far from LMR16020, AG9905/PoE, relays, W5500/RJ45 and the ESP32 antenna edge.
  • NFC keepout: no copper pours, power planes, GND planes, traces, stitching vias or components under the 13.56 MHz loop on any copper layer.
  • Connector mechanical access: verify in layout and CAM/mechanical review that every connector/terminal block is edge-mounted, faces outward, and has plug/cable insertion volume clear of components, mounting holes and neighboring connectors. RJ45 must be on an edge, not mid-board.
Export Gate
Do not order boards until live project context is restored and these pass:
  • ERC has no unresolved critical errors.
  • DRC has no airwires, missing footprints, invalid layers or cross-net copper overlaps.
  • Board outline is confirmed at 80 × 100 mm or the smallest necessary size not exceeding 120 × 100 mm.
  • Connector edge-access gate passes: RJ45, DC input, relay terminals, service USB, RS-485, Wiegand, inputs, GM861 connector and J101 are all on edges facing outward with unobstructed cable/plug insertion clearance.
  • H1–H4 mounting holes and all antenna/coil keepout zones are present in the PCB layout and visible in CAM/Gerber review.
  • U8 13.56 MHz loop, J101 125 kHz coil connector, C111/C112 and CLRC663 matching placeholders are placed at the presentation edge and away from PoE/DC-DC/relay/W5500 noise sources.
  • Gerbers are visually checked in a CAM viewer.
  • BOM includes all populated components for both power branches and Ethernet/Wi-Fi.
  • Pick-and-place rotations are checked for ESP32 module, W5500, RJ45/MagJack, AG9905-MTB, LMR16020, diodes/MOSFETs and polarized capacitors.
