The burner uses a MINI-USB interface to provide a stable physical connection. The device communicates with the computer using a serial port, and the baud rate is fixed at 1M (not changeable for the time being). The USB driver chip is CH340E, which is a common USB port to UARI chip. If the chip driver is not pre-installed, the burner will not be initially installed by the computer. For the first use, it is recommended to check the computer device manager to confirm that the burner can be recognized by the computer as a physical device.<br><br>Colour:black Material:PCB+Plastic Cable color random, don't accept the specified color The actual product may have slight color difference or difference, which will not affect the use<br><br>Package Contents: 1 * Burner 1 * cable<br><br>Only the above package content, other products are not included.
