The micro USB 3.0 motherboard interface has a dual interface with rolled edges, and the appearance is made of high-strength stainless steel with a hardware shell riveted together. Belongs to the horizontal micro mother seat series products. The product has four pins, which are welded to the PCB board during welding. There are 10 pins at the tail, which are gathered together by every 5 small pins, forming two 5-5 pin forms. The micro USB 3.0 motherboard supports current charging and data transmission. It is compatible and Backward compatibility. The left part is compatible with USB2.0, and the right part is compatible with USB3.0. SuperSpeed USB 3.0 is Backward compatibility. The theoretical maximum transmission speed can reach 5Gb/s, which is equivalent to downloading a 27GB 1080p high-definition movie in 43 seconds (the actual speed is not that fast). USB 3.0 is more energy-efficient because it only communicates with the USB host when it is ready for transmission, unlike USB 1.1/2.0, which is always in contact with the host. The product uses materials, hardware shell: high-strength stainless steel, plastic body: environmentally friendly and high-temperature resistant LCP plastic, pins: high conductivity copper. It can withstand repeated plugging and unplugging for over ten thousand times in terms of wear resistance life.
