This module has three kinds of level conversion chips on board, which can realize USB, TTL, RS232, RS485 four kinds of level free mutual transfer. ^^ Unique circuit design, no need to pass through the dip switch, can be automatically adjusted, wired ready to use ^^ The circuit board is only 8.3 cm X 3.0 cm, which has the advantages of small size and easy operation. ^^ Equipped with 500mA automatic recovery insurance, the current is greater than 500mA automatic disconnect, protect the equipment, reduce the risk of short circuit, to be connected back to normal circuit.
^^ The corresponding chip driver needs to be installed before use, which can realize the input of any port and the output of the other three ports at the same time.
