Product application: navigator, device, imaging device, for ROCK Pi 4 for MCU development board, -in USB device to extend the of adapter, convenient for USB supply and USB signal transmission of R handheld /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 materials with high frequency and low resistance. The PCB is made of . The PCB uses high plates. The thickness of the copper material is thickened to 1oz. The PCB circuit is strengthened and the of 2 5V core wires is strengthened, so the transmission current is more . Support up to 3A.Cable length The length of the wire refers to the part of the visible wire. It does not include the PCB and the connector.Colour: BlackMaterial: TPEandPCBSize: length about 30cmPackage Contents:1 x USB 3.1 type C to Type C Flat CableOnly the above package content, other products are not included.Note: Light and different displays may the color of the item in the a little different from the real thing.
