USB TTL uart RS232 RS485 4 Serial in 1 Module USB to Serial Module 6 Conversion in 1 Auto Converter Chip Fuse Wire USB to UART 232 485 FT232RL CH340 CP2102 able Choose (FT232RL)
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 8.3cm X 3.0cm, 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.
