I will design custom smartwatch hardware, pcb, firmware, ble, gps, display, sensors

A smartwatch packs an entire electronics system into a very limited space. I can develop the hardware and embedded software around the features your product actually needs, from sensing and positioning to wireless communication and the user display.

The development can include:

Custom smartwatch schematic and PCB layout

ESP32, nRF52, STM32 or other suitable MCU

BLE communication and GATT services

GPS/GNSS positioning and data handling

OLED, AMOLED, TFT or other display interfaces

IMU, heart-rate, SpO2, temperature and other sensors

Battery charging, protection and power management

Embedded C/C++ firmware and peripheral drivers

Sensor acquisition, filtering and device configuration

Compact component placement for wearable form factors

BOM, Gerbers, fabrication files and technical documentation

Whether you have a complete specification or only a block diagram, I can help translate the feature list into a practical electronics design. The hardware can be planned around your PCB dimensions, battery target, sensor requirements, connectivity and enclosure.

Provide your desired features, preferred MCU, display, sensors, GPS requirements and physical dimensions.
