آی سی مبدل USB به TTL سریال CH340G پکیج SOP16

Description:
CH340 is a series of USB bus adapters, that provides serial, parallel or IrDA interfaces over the USB bus (note: CH340G supports serial interface only). The CH340G integrate circuit provides common MODEM signals to allow adding a UART to a computer, or converting existing UART devices to USB interface. 
CH340 chip have built in USB bus pull-up resistors and on-chip signal termination, UD+ and UD- pins should be connected to the USB bus lines directly.

Application:
Serial converter
data transferring systems
