I’m building a prototype around a TrustZone-enabled Renesas MCU that must meet tight security requirements while handling 4 digital inputs, 4 digital outputs, 2 relays, 2 analog inputs, plus Bluetooth and Wi-Fi connectivity. Hardware and firmware are moving in parallel, but I now need extra horsepower on both fronts. On the hardware side the immediate focus is full-cycle support: schematic capture, board layout, prototyping, bench testing, and clean integration of every section—power, relays, analog front end, RF modules, and debug interfaces. Schematics and PCB files should be delivered production-ready with a complete BOM and clear test reports so I can push the design straight to a short run. Firmware must preserve TrustZone isolation and enforce restricted user logins while driving the peripherals and wireless stacks. Clean, well-documented C/C++ (or Renesas-preferred toolchain) is essential, along with OTA-friendly builds so future updates remain secure. Key acceptance points • Hardware: validated prototypes showing stable I/O, relay drive and analog accuracy, plus RF range tests over BLE and Wi-Fi. • Firmware: authenticated login flow, verified TrustZone boundary, reliable Bluetooth/Wi-Fi data exchange, and source code that compiles without warnings in the provided environment. Milestones will be split between board release, prototype test results, and firmware feature drops so progress stays easy to measure. If you have proven Renesas, TrustZone or similar secure-MCU experience and can jump straight into joint design reviews, let’s connect and lock in the timeline.

Hello, I can support this project end-to-end across both hardware and embedded firmware, with a strong focus on secure MCU-based product development, validation, and production readiness. On the hardware side, I can handle schematic capture, PCB layout, prototype bring-up, bench testing, BOM finalization, and production-ready release. I’m comfortable integrating mixed-signal sections including digital I/O, relay drivers, analog front ends, power, RF modules, and debug/programming interfaces while keeping the design practical for prototyping and short-run manufacturing. On the firmware side, I can develop clean, modular C/C++ code for peripheral control, analog acquisition, relay logic, BLE/Wi-Fi communication, and secure feature implementation around a TrustZone-enabled architecture. The focus will be on reliable system integration, maintainable code, and milestone-based validation. I’m comfortable joining design reviews immediately, working under NDA, and driving the project through board release, prototype validation, and firmware feature milestones. I can start right away and share relevant PCB/embedded examples from my portfolio.
