Introduction:\u00a0<\/h2>

Why\u00a0<\/span>Protocols\u00a0<\/span>Matter<\/span><\/h2>

In the rapidly evolving e-mobility industry, the choice of communication protocol between the motor controller and the display is critical. A stable and reliable protocol ensures real-time information for riders, reduces after-sales issues, and accelerates product development. All Haytrix displays use the UART No.2 protocol to provide consistent, dependable performance for manufacturers and distributors.<\/p>

Protocols are essentially the “language” between devices. If the controller and display don\u2019t speak the same language, riders may experience unstable readings, delayed responses, or even system malfunctions. These issues can lead to customer complaints, higher warranty costs, and delays in product launch.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

What\u00a0 \u00a0is\u00a0\u00a0UART No.2 Protocol<\/span><\/h2>

UART, or Universal Asynchronous Receiver-Transmitter, is a serial communication protocol allowing devices to send and receive data sequentially without a shared clock. The No.2 variant is optimized for e-bike and e-scooter displays, providing enhanced stability, lower error rates, and seamless Bluetooth integration for mobile apps.<\/p>

Step-by-Step Data Flow<\/h2>

  1. The motor controller measures speed, battery level, and assist mode.<\/p><\/li>

  2. Data is packaged into UART No.2 frames.<\/p><\/li>

  3. The display receives and interprets the data.<\/p><\/li>

  4. Riders see real-time speed, battery, and power assist levels.<\/p><\/li>

  5. Optional Bluetooth modules forward data to mobile apps.<\/p><\/li><\/ol>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    UART No.2 vs CAN vs BLE<\/h2>

    While UART is widely used, other protocols like CAN bus and Bluetooth Low Energy (BLE) are also found in electric mobility systems. Each has its advantages and drawbacks:<\/p>
