RS485 to TTL Serial Level Signals Converter Module - MAX485

  • Was  RM11.00 
  • RM6.50

  • Product Code: RS485 to TTL
  • Availability: In Stock

RS485 to TTL Module (supporting EIA-485 standard) is for long range, high data rate error prone differential communication. Digital communications networks implementing the EIA-485 standard can be used effectively over long distances and in electrically noisy environments. Multiple receivers may be connected to such a network in a linear, multi-drop configuration. These characteristics make such networks useful in industrial environments and similar applications.


Specifications:

  • Features MAX485 chipset
  • Working Voltage: 5V
  • 5.08mm (0.2″) pitch, 2-pin terminals for RS-485 easy communication and wiring
  • 4-pin 2.54mm (0.1″) pitch headers for RS485 and Power
  • 4-pin 2.54mm (0.1″) pitch headers for DI,DE,RE,RD signals
  • PCB Board Size: 44 x 14mm

 

Applications

  • Multi-drop wired communication System, requiring multiple nodes needing to talk to each other.
  • Long distance error prone wired communication
  • High data rate wired communication

 

 

MAX485 IC.
This IC will take RS232 signals and perform the voltage level conversions required to turn them into 485 signals.

Pin-out:

  1. RO - Receiver out
  2. RE - Receiver enable (enabled when this pin is LOW)
  3. DE - Driver enable (enabled when this pin is HIGH)
  4. DI - Driver in (the transmitter pin)
  5. GND - Ground (0V)
  6. A - Connect to pin A of the other 485 IC
  7. B - Connect to pin B of the other 485 IC
  8. Vcc - Power, in my case +5V
