The RS485 signal flow control is more troublesome when writing programs, especially in unfixed data communication. If you do not know how much data is for each packet of data, it is unclear when switching between receiving and transmitting direction. The MT485S automatic flow control module can solve this problem completely.
This module supports 500 kbps and the following baud rates. It can support automatic flow direction conversions such as 2400bps, 4800bps, 9600bps, 19200bps, 38400bps, 57600bps, 115200bps, 128000bps, 256000bps, etc.
