USB (Universal Serial Bus) connector is a standard interface for universal data transmission and power supply, supporting hot swapping and multi protocol compatibility. It is widely used in consumer electronics, industrial equipment, and smart terminals. From USB 2.0 to USB4, its iterative upgrades have significantly improved transmission rates (up to 40Gbps) and power supply capabilities (up to 240W), becoming the core components of modern device interconnection.
Mobile phone/computer:Type-A and Type-C interfaces are used for data transfer and fast charging (such as USB PD).
Peripheral Connection:Connect peripherals such as keyboard, mouse, printer, etc., supporting plug and play.
Industrial control
Device communication:Connect industrial sensors and PLC through USB to RS485/232 module.
Firmware upgrade:Provide a stable program burning channel for embedded devices.
On board system
Intelligent cockpit:Type-C interface supports 4K video transmission and high-power charging (such as USB-IF vehicle certification).
