CH9350L Dual USB Master to MCU Serial interface.

Description:

CH9350L is a USB keyboard and mouse to UART communication control chip. Combined with the 

simple and easy-to-use features of UART, the USB communication method between USB keyboard/mouse 

and USB host can be extended to UART, which is convenient for data integration with audio, video and 

other signals, or can be directly extended through 485 signal 2-wire, which is mainly used for KVM 

extension, KVM switching, KM synchronization and other applications.
