Bluetooth Tracker PCB & Firmware
Budget: $250 – $750 USD
I’m building a tiny Bluetooth-based tracker that can register with Google’s “Find My Device” network and broadcast its presence so an Android phone can locate it. I need the complete hardware design and embedded code, from concept through ready-to-manufacture files.
Core requirements
• The board’s sole purpose is tracking; no extra sensors or radios are necessary.
• Advertising must follow the Find My Device (FMD) protocol so the tag is discoverable and reportable by nearby Android phones.
• Bluetooth Low Energy is the only wireless link; long battery life and low stand-by current are critical.
• I’m flexible on the microcontroller: nRF52, ESP32, or another BLE SoC is fine as long as it meets Google’s FMD spec and you can supply a proven toolchain.
What I expect to receive
1. Schematic, PCB layout, and Gerber/ODB++ files ready for fabrication, created in KiCad, Altium, or Eagle.
2. A concise BOM with part numbers that are currently in stock at mainstream distributors.
3. Production-ready firmware (C/C++ using the vendor SDK, Zephyr, or ESP-IDF) plus full source, build instructions, and a compiled binary.
4. Programming and bring-up guide so I can flash and test the first prototypes.
5. Validation steps showing that the board advertises correctly and is detected by Android’s Find My Device app.
I’ll handle enclosure design and final mass-production; you focus on delivering reliable electronics and code I can build on.
