Smart Outdoor LED Controller: USB-PD

Smart Outdoor LED Controller: USB-PD Powered & 45-Day Turnkey IoT Delivery

Project Description [ The Challenge & Rapid Delivery ] The client required a modern, reliable, and cost-effective outdoor lighting solution with a highly aggressive timeline. Leveraging my integrated engineering team and Shenzhen-based supply chain, we completed the entire cycle in just 45 days: PCBA Layout → Prototyping(EVT) → Hardware Validation(DVT) → App Development → Cloud Deployment → Pre-Production(PVT/PP) → Mass Production(MP).

[ Technical Innovations ] USB-PD Power Integration: Engineered a PD Trigger (Decoy) circuit, allowing users to power 12V/24V LED strips using standard, off-the-shelf USB-C PD chargers or power bank. This eliminates bulky, proprietary power adapters and reduces shipping/packaging costs. Deep Optimization (IoT Edge Computing): Performed low-level programming on the CH591 BLE chip. By running complex logic and GPIO control directly on the BLE chip, It eliminated the need for an external MCU. This reduced the BOM cost, lowered power consumption, and minimized potential failure points. Full-System OTA: Integrated seamless Over-the-Air (OTA) updates via the mobile app, ensuring long-term feature scalability and drastically reducing after-sales maintenance costs.

[ Manufacturing & O&M ] Full-Scale Mass Production: As the client lacked in-house manufacturing capabilities, I currently manage the ongoing mass production, ensuring Tier-1 quality control and stable supply chains logistics. End-to-End Infrastructure: Built and currently maintain the secure backend server and mobile application ecosystem for real-time device management.

[ Value to Clients ] I provide high-speed, low-cost IoT edge computing solutions. By consolidating hardware functions and utilizing universal power standards, I helped the client launch a market-ready, "Certified-level" product in record time, moving from a concept to a revenue-generating mass-produced item in less than 7 weeks.
