Product application: GPS navigator, storage device, imaging device, for ROCK Pi 4 for Raspberry Pi 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, the signal is pure, there is no signal attenuation interference problem of parasitic capacitance and parasitic inductance, and there is no CAF Mini short circuit phenomenon, and the product is durable. The PCB is made of high-quality materials with high frequency and low resistance. The PCB is made of precision. The PCB uses high TG plates. The thickness of the copper material is thickened to 1oz. The PCB power circuit is strengthened and the use of 2 5V power core wires is strengthened, so that the transmission current is more powerful. Support up to 3A. Cable length Description: The length of the wire refers to the part of the visible wire. It does not include the PCB and the connector. Colour: Black Material: TPE+PCB Size: length about 30cm Package Contents: 1 x USB 3.1 type C to Type C Flat Cable Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
