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 for SLR handheld/tilt, etc. The differential signal design has no via holes, ensuring pure signal transmission without interference from parasitic capacitance or parasitic inductance, and avoids CAF-related short circuit issues. The product is durable. The PCB is made of high-quality materials with high frequency and low resistance. The PCB uses high-grade boards with copper thickness increased to 1oz, strengthening the 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, excluding the 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 variations in color compared to the actual item. Measurement allows an error of +/- 1-3cm.
