USB-RS422-PCBA FTDI USB to RS485 Embedded Converter PCB Assy
Product Description
USB-RS422-PCBA
The USB-RS422-PCBA converter provides a USB to RS422 serial interface with a simple USB type A connector and PCB for easy integration into a design or as the basis of a converter cable.
An FT232RQ USB to serial UART interface IC handles all the USB signalling and protocols.
The integrated electronics also include the RS422 transceiver plus Tx and Rx LEDs which give a visual indication of traffic of Tx and Rx.
The PCB is FCC, CE, RoHS compliant.
