Bluetooth Jobs

I need a production-ready printed circuit board for a compact consumer-electronics tracker. The board has to combine Bluetooth connectivity for smartphone pairing, GNSS positioning for global location data, a LoRa module for long-range updates, and a 3-axis motion sensor to wake the unit only when it moves. Everything will run from a single rechargeable battery, so careful power budgeting and a low-power microcontroller are essential. Form-factor will be small enough to slip into a key-tag style enclosure, so component height and antenna placement must be considered from the start. I’m flexible on the exact silicon—Nordic, Espressif, STM, Semtech, etc.—as long as you can justify part choice against current draw, cost and global availability. Please take the design from ...
