MAX 485 Module / RS- 485 Module / TTL to RS- 485 Converter Module For Arduino - Techtonics

MAX 485 Module / RS- 485 Module / TTL to RS- 485 Converter Module For Arduino

  • Rs. 90.00 INR



  • Uses MAX485 chipset.
  • On-board MAX485 chip, A low power consumption for the RS-485 communication, slew-rate limited transceiver.
  • On board then 5.08 (mm) pitch 2P terminal to facilitate RS-485 communication wiring. 
  • All pins of chip have been lead to can be controlled through the micro controller. 
  • Working voltage: 5V. 
  • Board size: 44 (mm) x 14 (mm).



  • On-board MAX485 chip is a low-power and slew-rate-limited transceiver used for RS-485 communication.
  • It works at a single +5V power supply and the rated current is 300 μA. Adopting half-duplex communication to implement the function of converting TTL level into RS-485 level, it can achieve a maximum transmission rate of 2.5Mbps.
  • MAX485 transceiver draws supply current of between 120μA and 500μA under the unloaded or fully loaded conditions when the driver is disabled.
  • The driver is limited for short-circuit current and the driver outputs can be placed at a high impedance state through the thermal shutdown circuit.
  • The receiver input has a fail-safe feature that guarantees logic high output if the input is open circuit. In addition, it has a strong anti-interference performance


  • Low-Power RS-485 Transceivers
  • Low-Power RS-422 Transceivers
  • Level Translators
  • Transceivers for EMI-Sensitive Applications
  • Industrial-Control Local Area Networks
