Description Product Usage: GPS navigator, storage device, image processing unit, for ROCK Pi 4 for Raspberry Pi MCU development board, embedded USB device to expand 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 with parasitic capacitance and parasitic inductance, and there is no CAF Mini short circuit problem, and the product is durable. The circuit board is made of high-quality materials with high frequency and low resistance. The circuit board is made with precision. The circuit board uses high TG plates. The thickness of the copper material is thickened to 1oz. The circuit board's power circuit is strengthened, and the use of 2 5V power cores is strengthened, so that the transmission current is more powerful. Supports up to 3A. Cable length Description: The length of the wire refers to the part of the visible wire.
