I already have a complete schematic for a multi-function meter built around the STM32H743BIT6. Before I move to PCB layout I need a fresh set of eyes to refine the design, swap a few key parts, and fold in two new capabilities. Work required • Correct any schematic errors you spot (net ties, pin assignments, power flags, ERC issues). • Replace the specified parts—new values for several resistors and capacitors plus an updated pin-compatible MCU revision. • Add extra sensing channels and tighten the power-management section so the board runs cooler and meets my standby-current target. • Schematic circuit diagram design and PCB Design in Altium software. We may provide Altium software. • Simulation required in Proteus software. We may provide software. • Testing support of products Deliverables 1. Updated schematic in the same CAD format I provide (Altium files) with all changes clearly annotated. 2. Clean BOM showing new part numbers and footprints. 3. Brief change log highlighting every correction, replacement, and the additions for the new sensors and power circuitry. 4. ERC report with zero critical errors. Acceptance criteria The file must open without warnings in Altium 24, compile with no electrical-rule violations, and keep the overall board outline and connector placement untouched so it drops straight into my existing PCB project. If this is the kind of quick yet detail-oriented schematic work you enjoy, let’s get started—I can share the current design the moment we agree on the hand-off protocol.
