The AH500 series CPU module provides a standard USB 2.0 interface. USB 2.0 increases
the data transfer rate, and decreases the time it takes to download the program, monitor the
program and configure the hardware. Besides, users do not need to buy a communication
cable for the CPU module. They can use a general USB cable to connect to the AH500 series
CPU module.
