KNACRO MAX3485 5V RS485 to TTL Signal Mutual Conversion Module for Arduino Overvoltage protectionWith Signal Indicator Package 5V 2Pcs

1, The module uses all industrial MAX485ESA chip 2, With 485 signal overvoltage protection 3, With a signal, power LED indicator, send and receive situation panoramic view 4, With 120 ohm termination resistor strobe function, long-distance communication, can be directly shorted 5, The module will be 485 signal to the MAX485 signal can withstand the common-mode voltage of -7 to +12 V, the module can be solved as a result of the 485 signal common-mode voltage is too high, resulting in 485 burn or heat problems. 6, The module uses tantalum electrolytic capacitors to filter the power supply, the power quality better. 7,The module pin pin can be directly inserted in the hole plate 2.54 pitch for easy development 8, Our all modules have to undergo a rigorous test to ensure quality 9, The back of the module with a wiring diagram, to facilitate your use Package Included: 2xRS485 to TTL Signal Mutual Conversion Module If you have any question , please feel free to contact us.
