Product application: GPS navigator, storage device, imaging device, for ROCK Pi 4 and MCU development board, built-in USB device to extend adapter functionality, convenient for USB power supply and signal transmission for SLR handheld pan/tilt systems. Differential signal design without via holes ensures pure signal transmission, minimizing interference from parasitic capacitance and inductance, preventing CAF-related short circuits, and enhancing product durability. PCB constructed with high-quality materials for high-frequency performance and low resistance. Precision-made using high TG PCB boards with 1oz thickened copper layers for improved circuit strength. Reinforced with dual 5V core wires to support stronger current transmission, capable of up to 3A. Cable length refers to the visible wire portion only, excluding PCB and connector. Color: Black Material: TPE + PCB Size: Approximately 30cm in length Package Contents: 1 x USB 3.1 Type-C to Type-C Flat Cable Note: Other items not included. Lighting and display differences may cause slight color variations between image and actual product. Measurement tolerance: +/- 1-3cm.
