I will design wearable sensor pcb with gps, imu, ble and embedded firmware

Need a wearable that tracks location and motion and talks to a phone? I design the board and write the firmware, so one engineer owns your whole prototype.

What you get:

• Schematic and 2 to 6 layer PCB layout sized for small wearable enclosures
• GNSS module, 6 or 9-axis IMU and BLE SoC integration (nRF52840, ESP32 family, STM32WB)
• Power path: LiPo charging, fuel gauge, sleep-current budget
• Antenna placement, RF matching and keep-out guidance
• Embedded C/C++ firmware: sensor drivers, GNSS and motion scheduling, BLE GATT service, OTA-ready bootloader
• Gerber, BOM, pick and place, 3D STEP and editable source files
• Bring-up notes and a test report

Built for fitness, sports, pet and asset trackers and health wearables.

Message me first with your sensor list, battery size and target board size so I can confirm scope and price.
