Product application: GPS navigator, device, imaging device, for ROCK Pi 4 for MCU development board, USB device to extend the adapter, convenient for USB power supply and USB signal transmission of SLR handheld / tilt, etc. The differential signal has no via hole design, ensuring pure signal transmission with no interference from parasitic capacitance or inductance, and avoids CAF mini short circuit issues. The product is durable. The PCB is made of high-quality materials with high frequency and low resistance. High-grade PCB materials are used with increased copper thickness of 1oz, strengthening the PCB circuit and enhancing the 2.5V core wires for improved current transmission. Supports up to 3A. Cable length refers to the visible wire portion only and does not include the PCB or connector. Color: Black Material: TPE + PCB Size: approximately 30cm Package Contents: 1 x USB 3.1 Type C to Type C Flat Cable Only the above package content is included; other products are not included. Note: Lighting and different displays may cause slight color differences compared to the actual item. Measurement allows an error of +/- 1-3cm.
