FPC OLED Smart Watch Based on CH583M

This project will develop an OLED smartwatch based on the CH583M microcontroller, featuring multiple practical functions, including activity tracking, temperature measurement, and Bluetooth communication. Utilizing FPC (Flexible Printed Circuit) materials, this watch not only meets complex design requirements but also maintains a slim and lightweight profile, seamlessly integrating into daily wear scenarios.

Key Components and Features

The development of this OLED smartwatch revolves around several crucial components, each carefully selected to ensure optimal performance and functionality:

1. 
   
2. Main Controller: CH583M
3. Clock Speed: 60MHz
4. Memory: 512KB Flash, 32KB RAM
5. Connectivity: Bluetooth 5.0 BLE (supports low-power wireless communication)
6. The CH583M, as the core processor of the watch, delivers strong computational performance and supports Bluetooth 5.0, enabling seamless data exchange with other smart devices.

1. Display: OLED 128×64
2. Resolution: 128×64 pixels
3. Interface: 4-wire SPI
4. The OLED screen offers high contrast and low power consumption, clearly displaying time, fitness data, temperature, and other information, making it ideal for low-power devices.

1. Gyroscope: ICM20608
2. Interface: SPI & I2C
3. The ICM20608 gyroscope accurately measures wrist movements, providing data support for activity tracking. It communicates with the main controller via SPI/I2C, transmitting motion data in real time.

1. Independent Buttons: 2
2. Two buttons allow for device control, such as switching display modes or adjusting settings, simplifying user interaction.

1. ADC: NTC Temperature Sensor & Battery Voltage Measurement
2. The NTC temperature sensor monitors the wearer’s body temperature and displays real-time readings.
3. Battery voltage measurement ensures sufficient power, preventing sudden shutdowns.

1. FPC (Flexible Printed Circuit) Material
2. The use of FPC makes the watch thinner, more flexible, and foldable, ensuring comfortable wear on the wrist.
3. FPC enables a compact internal layout, minimizing space usage.

FPC from JLCPCB

To begin the project, we will source the FPC materials from JLCPCB, which offers FPC starting at just $2, supporting any shape and size. This flexibility allows for a custom design that perfectly fits the requirements of the smartwatch, ensuring both functionality and comfort.

This OLED smartwatch, built around the CH583M microcontroller and utilizing FPC materials, promises to be an innovative and practical device for everyday use. With features like activity tracking, temperature measurement, Bluetooth connectivity, and a compact, lightweight design, this smartwatch is set to offer an excellent user experience while maintaining long-lasting battery life and comfortable wearability. The use of advanced components, such as the CH583M microcontroller, ICM20608 gyroscope, and OLED display, will provide users with reliable performance and a stylish design that can easily be incorporated into daily life.

We are excited to bring this cutting-edge technology to life and look forward to the successful development of the smartwatch.
