Product application: GPS navigator, device, imaging device, for ROCK Pi 4, MCU development board, USB device to extend adapter for USB power supply and USB signal transmission of SLR handheld/tilt. The differential signal design has no via holes, ensuring pure signal transmission without interference from parasitic capacitance or parasitic 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 boards are used with copper thickness increased to 1oz. The PCB circuit and 2.5V core wires are reinforced for improved current transmission. Supports 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. Only the above package content is included; other products are not included. Note: Lighting and different displays may cause slight color variations compared to the actual item. Measurement allows an error of +/- 1-3cm.
