The TTL to RS485 Module, RS485 to TTL signal with Automatic Flow Control is a versatile device designed to facilitate seamless communication between TTL and RS485 signals. It simplifies the conversion process, making it as straightforward as operating a standard serial port. This module is compatible with both 3.3V and 5.0V power supplies and signals, offering flexibility in various applications.

Features:

• This module fully considers the 485Bus lightning protection design, anti-jamming design, in the field of long-distance transmission, the module of the "ground" connected to the earth, can play a very good anti-jamming and lightning protection role. Indoor short distance transmission cannot be grounded.
• The standard 2.54 spacing design is adopted to facilitate your secondary development
• There is a matching resistance of 120 ohms, short RO can match the resistance, it is recommended for long-distance transmission.
• Support multi-machine communication, can access the bus up to 128A equipment
• This module c an be hot-swappable, no other 485Chip signal connector hot-swappable phenomenon.
• Large area of copper to prevent signal interference.
