Product application: GPS navigator, storage device, imaging device, for ROCK Pi 4 for MCU development board, built-in USB device to extend the use of adapter, convenient for USB power supply and USB signal transmission of SLR handheld pan/tilt, etc. The differential signal has no via hole design, ensuring pure signal transmission without interference from parasitic capacitance or inductance, and avoids CAF mini short circuit issues; product is durable. The PCB is made from high-quality materials with high frequency and low resistance. Precision manufactured using high TG plates with 1oz thickened copper material. The PCB circuit is reinforced with dual 2.5V core wires to support stronger current transmission, supporting 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: Light and display differences may cause slight color variations between image and actual item. Measurement allows for an error of +/- 1-3cm.
