RS485 to TTL converter
With this board you can connect your microcontroller serially that’s far away from each other than this module interfaces RS-485 to TTL or vice-versa.It has Auto Direction control, making it easier to use as RS-232/TTL Serial Interface replacement. RS485 is used for Serial Communications over longer distances. The converter is designed for office and industrial applications (non-isolated), and provides superior characteristics/features normally found only on more expensive units.
