Dual serial port tool made by ch342f, used for daily debugging
I have open sourced a ft2232d dual serial port tool before, but the chip is a bit expensive, so I remade this one. The peripherals are simple and the cost is relatively low. I have simply tested the 3M baud rate and there is no problem.
