Product application: GPS navigator, storage device, imaging device, for ROCK Pi 4 for MCU development board, built-in USB device to extend the use of adapter, convenient for USB power supply and USB signal transmission for SLR handheld pan/tilt, etc. The differential signal has no via hole design, ensuring pure signal transmission without signal attenuation or interference from parasitic capacitance and inductance, and avoids CAF-related short circuit issues; product is durable. The PCB is made from high-quality materials with high-frequency performance and low resistance. Precision manufacturing uses high TG PCB boards with thickened copper material (1oz), reinforcing the circuit. Dual 2.5V core wires enhance current transmission, supporting up to 3A. Cable length refers only to the visible wire portion, 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 Note: Light and display differences may cause slight color variations between the image and actual item. Measurement error allowance is +/- 1-3cm.
