I need a production-ready KiCad project that captures the entire electronics of a low-power Wi-Fi/BLE smart safety watch. The schematic must pull together every subsystem – radio, sensing, power and user-interface – into one cohesive, ERC-clean design I can take straight into layout once I sign off. Core hardware blocks you must include • Dual-mode Wi-Fi + Bluetooth LE module • MEMS microphone and compact camera for image & audio capture • 6-axis IMU with fall/motion-detection interrupt lines • SOS trigger circuitry and vibration motor / buzzer driver • Color display interface, external flash and USB-to-UART/USB-C charging port • Li-ion cell, charger IC, fuel-gauge, power-tree with deep-sleep rails • Robust OTA firmware-update paths (boot pins, reset, strapping, etc.) The most critical functionality is rock-solid wireless connectivity working hand-in-hand with camera, microphone, OTA, SOS and fall-detection features, so please route those pins and supporting passives with extra care and leave clear notes where RF or power integrity is sensitive. Deliverables I expect • Editable KiCad 6/7 schematic file set, ERC-clean • Complete pin map and interface list • Preliminary BOM with part numbers and key specs • Hierarchical power-tree diagram showing all rails and quiescent currents • RF and power design notes (PDF or within the schematic) focused on layout guidelines • Detailed documentation of every schematic connection so firmware can begin immediately Do not begin PCB layout until I give written approval. When you send your proposal, I will prioritise bids that showcase previous wearable or IoT work, outline your chosen MCU / radio platform, explain how you will integrate the camera and mic, describe your OTA approach, provide a realistic timeline and demonstrate clear KiCad experience. I’m ready to move quickly once the right engineer is on board.

Hi, I can develop the complete production-ready KiCad 6/7 schematic for your Wi-Fi/BLE safety watch, with PCB layout starting only after your written approval. I propose an ESP32-S3-based architecture for integrated Wi-Fi/BLE, OTA, USB, camera, microphone, IMU, display and external flash. I will carefully handle boot/strapping, EN/reset, USB-UART and recovery paths so firmware updates remain reliable. The schematic will cover: * ESP32-S3 Wi-Fi/BLE + RF support * Camera + MEMS microphone * 6-axis IMU with fall/motion interrupts * SOS button + vibration/buzzer driver * Color display + external flash * USB-C + charging + USB-UART * Li-ion charger + fuel gauge * Low-Iq regulators and deep-sleep power rails * Decoupling, ESD/TVS and protection Deliverables include an ERC-clean hierarchical KiCad project, complete pin/interface map, preliminary BOM with manufacturer part numbers, hierarchical power tree with rail/Iq information, RF/power integrity notes and detailed connection documentation for firmware development. I have hands-on experience designing ESP32 embedded hardware, KiCad schematics/PCBs, power systems, interfaces and production-oriented BOMs. Timeline: approximately 5–7 days for schematic and documentation, depending on final component requirements. I will not start PCB layout until you give written approval.
