This is exactly the kind of modernization project I can support — preserving the mechanical/electrical integration of the original system while replacing obsolete components with a maintainable STM32-based architecture. My approach would keep the original board dimensions, mounting pattern, connector alignment, and cabinet compatibility intact while redesigning the electronics around a modern STM32 MCU with native USB, updated power regulation, protected I/O, and improved audio/control architecture. I can replace the PIC18 + FT232 chain with a cleaner STM32 USB design, integrate a modern DSP/audio codec solution, redesign the coin/mech interfaces with proper opto-isolation and protection, and remove the outdated video/RCA/inverter sections while preserving amplifier and service interfaces. The final result would be a production-ready drop-in replacement with modern components, easier firmware maintenance, better protection/EMC behavior, and long-term component availability.

Hi there, I’ve carefully read your project description, and I can help redesign your legacy PCB into a modern drop-in replacement while preserving the original board size, mounting holes, USB-B position, connectors, and required interfaces. I’m Samuel Tshibangu, a mechatronics engineer with hands-on experience in PCB redesign, STM32-based hardware, USB, audio circuits, power regulation, opto-isolated inputs, MOSFET drivers, protection circuits, and custom firmware support. I’ve already worked with the key technologies mentioned, including STM32, native USB, audio codec/DSP integration, coin-input protection, and mixed-signal PCB layouts. I can modernize the design using current components, remove the obsolete PIC/FTDI/video sections, and deliver clean schematic, PCB layout, BOM, Gerbers, and firmware-ready hardware documentation. Feel free to send me the original schematic and mechanical constraints, and I can start right away. Best regards, Samuel Tshibangu

HI, KINDLY READ THROUGH MY PROPOSAL I will deliver a complete modern redesign of your legacy PCB as a drop-in replacement, keeping the exact board size (168 × 206 mm), mounting holes, and critical connector positions while upgrading to current components and improved reliability. MY APPROACH ✅ Phase 1: Full review of your existing schematic, identify all functions to preserve, and map to modern equivalents. ✅ Phase 2: New schematic using STM32 (with native USB), modern audio DSP/codec, opto-isolated coin inputs, robust power regulation, MOSFET drivers, and full ESD/reverse-polarity protection. ✅ Phase 3: Optimized 4-layer PCB layout maintaining original form factor, with improved grounding and signal integrity. RELEVANT PROJECTS • Several legacy-to-modern PCB redesigns for arcade/gaming machines and industrial controls (PIC to STM32 migration, audio upgrades, native USB, protected inputs first-pass success at JLCPCB). DELIVERABLES • Complete KiCad/Altium schematic and PCB layout files • Gerber RS-274X, drill, pick-and-place files • Updated BOM with current components and sources • Design notes and migration guide QUESTIONS 1. Can you share the full legacy schematic and any mechanical drawings now? 2. Preferred EDA tool (KiCad or Altium)? 3. Target STM32 series (e.g. STM32F4, STM32H7, etc.) and audio codec preference? Ready to start immediately. I can deliver the first schematic draft quickly after receiving the files.

@tetianam8

⭐⭐⭐⭐⭐ I've carefully reviewed your requirements, and this is exactly the kind of project where a thoughtful redesign is far more important than a simple schematic conversion. Your goal is not to clone the existing board, but to create a modern drop-in replacement that preserves mechanical compatibility while eliminating obsolete components and improving reliability, protection, and long-term maintainability. I can assist with: • Full review and interpretation of the legacy schematic • STM32-based architecture selection and migration strategy • Native USB implementation replacing the FT232RL • Modern audio DSP/codec integration to replace the TDA7465 platform • Opto-isolated coin inputs and protected I/O design • Modern power regulation, ESD, and reverse-polarity protection • PCB layout maintaining board dimensions, mounting holes, USB position, and connector locations • Manufacturing-ready schematic, PCB, BOM, and Gerber package A few questions: Will firmware development be part of this phase, or is the hardware redesign the primary objective? Do you have the original PCB files, or only schematics? Is there a preferred STM32 family (F4, G4, H7, etc.), or should I select based on requirements? This modernization approach can preserve full drop-in compatibility while giving you a platform that remains supportable for years to come.
