UHS Bus Interface

UHS-I provides faster bus speed using just one row of pins, while UHS-II uses two lanes for even faster data transfer via two rows of pins. The symbol “I” means UHS-I, and “II” means UHS-II. Please make sure your device supports the same standard to benefit from the increased speeds.
