Created 204 route segments and 22 vias
- Replace the removable ESP32 approach with a fixed onboard ESP32 implementation
- Define the board-level requirements for WiFi-only telemetry through the onboard ESP32
- Capture external power-input requirements for operation from either 5 V or 12 V
- Capture the machine harness interface requirements for money-in and money-out signals
- Capture the need for BOOT and RESET user-accessible service controls
- Capture manufacturability and layout-style requirements inspired by the sample photo
- Document ambiguities and information still required before schematic and PCB decisions are made
- Detailed circuit topology decisions
- Final connector part selection
- Final protection, isolation, or signal-conditioning method
- Final regulator architecture
- Firmware implementation details beyond high-level interface needs
- Regulatory or certification documentation
- Power input from machine: 5 V or 12 V source
- Telemetry path: wireless internet connectivity through onboard ESP32 only
- Machine I/O: money-in harness input and money-out harness input
- Service interface: BOOT and RESET buttons
- Mechanical intent: manufacturable PCB with placement/style direction informed by the attached sample photo
- The design shall use a fixed onboard ESP32 rather than a removable ESP32 module.
- The ESP32 shall be the board's only intended wireless internet interface.
- The board shall operate from either a 5 V input or a 12 V input supplied by the machine.
- The board shall accept two machine-originated telemetry-related inputs: money-in and money-out.
- The board shall include BOOT and RESET controls for bring-up, programming, and recovery.
- The board shall be suitable for practical PCB fabrication and assembly.
- The PCB layout direction shall be visually informed by the attached sample photo, subject to final mechanical constraints.
- The money-in and money-out signals shall remain configurable requirements until their exact voltage, polarity, source type, and reference scheme are confirmed.
- The machine-side power-input connector and signal harness details shall remain open requirements until the exact mating hardware is identified.
- The onboard ESP32 requirement shall be refined to a specific ESP32 family or variant once software, RF, memory, and provisioning needs are confirmed.
- The board should target standard prototype-friendly PCB fabrication and assembly.
- The sample photo should be treated as a style and arrangement reference, not yet as a locked mechanical copy.
- Mechanical requirements still need confirmation for board outline, mounting, connector orientation, button accessibility, and any enclosure or harness clearance limits.
- Record the architectural shift from removable ESP32 module to fixed onboard ESP32.
- Record that all network connectivity is now wireless through the ESP32 only.
- Remove any remaining requirement assumptions that depend on a removable module or non-ESP32 networking path.
- Confirm what the machine provides for input power: allowed nominal voltages, tolerance, polarity expectations, and whether both 5 V and 12 V are possible in the same product family or on the same harness.
- Confirm the harness definition for money-in and money-out as far as currently known: signal names, common return/reference, expected event behavior, and connector ownership.
- Explicitly mark unknown signal-electrical details as blockers for later circuit definition rather than guessing them now.
- Confirm that the ESP32 is fixed on the PCB and not user-removable.
- Confirm the required wireless role at a high level: WiFi telemetry to a backend service.
- Capture any still-open product requirements that affect ESP32 selection, such as provisioning method, expected RF environment, memory needs, antenna constraints, or service access expectations.
- Define BOOT and RESET as required board-level service functions.
- Confirm whether the buttons are intended only for development/service access or also for field access.
- Capture any need for programming, test, or debug access that should coexist with those buttons.
- Use the attached sample photo as a visual reference for board style, connector/button accessibility, and general placement priorities.
- Treat any dimensions, hole locations, and connector spacing as unconfirmed until measured or specified.
- Record manufacturability as a first-class requirement so the final layout favors standard fabrication and assembly processes.
- Create an explicit list of unanswered integration questions.
- Separate "must know before schematic capture" items from "can be resolved during layout refinement" items.
- Avoid locking in circuit choices until these questions are answered.
- What is the exact voltage range of the money-in and money-out signals?
- Are the money signals referenced to machine ground, open-collector/open-drain style, actively driven, AC-like pulses, or something else?
- What are the expected pulse width, frequency, idle state, polarity, and noise environment for each harness signal?
- Is there one physical connector for power and both money signals, or separate harnesses?
- What connector family, pin order, and pin labeling must the PCB support?
- Which ESP32 family or exact part should be treated as the product target?
- What antenna placement constraints, keepout needs, or enclosure limitations apply to the fixed onboard ESP32 approach?
- Are BOOT and RESET intended to be reachable only during bench service, or in the installed product?
- What exact features from the sample photo are mandatory versus only inspirational?
- Are there board-size, mounting-hole, standoff, or enclosure constraints not yet documented?
- The project documentation clearly states that the ESP32 is onboard and fixed.
- The project documentation clearly states that connectivity is wireless through the ESP32 only.
- The project documentation clearly captures dual-voltage power-input intent at the requirements level.
- The project documentation identifies money-in and money-out as external machine interfaces while explicitly flagging their electrical ambiguity.
- The project documentation records BOOT and RESET as required service features.
- The project documentation records manufacturability and sample-photo-inspired layout intent without prematurely locking detailed circuit or PCB decisions.
- The remaining unknowns are listed clearly enough to drive the next round of stakeholder clarification.
