Features: Adopt nec720201 master chip, high-speed computing core, high compatibility. The card is equipped with a 2A power supply and does not require an external power supply. The 330 12X12mm inductor is superior to the 100 10X10mm inductor. Each interface is equipped with a separate interface protection fuse, which cuts off the power immediately when the external USB is short-circuited or over-current, protects the external device and the computer from damage, and automatically returns to normal after troubleshooting. Each interface is equipped with an independent voltage regulator capacitor to ensure smooth power supply without interface. It can also withstand 250 °C with Solid chip capacitors and has high durability. The immersion gold process has good electrical conductivity and strong anti-oxidation ability, which can ensure stable transmission. Fast data transmission speed, can up to 5Gbps.
