Package Included

- 1 x MAX485 RS485 Transceiver Module

Description:

- Maxim MAX485 IC allows serial communication over very long cable runs (1200 meters). 
- Serial data can be transmitted in both directions (half duplex) at a data rate up to 2.5Mbps.
- The modules operate from a standard 5V power supply and use 5V logic levels allowing them to be interfaced to the hardware serial ports of microcontrollers such as Arduino/PIC etc.
- Direction of communication can be controlled with just one digital pin.
- Multiple modules together for communication between 2 or more devices.
- For even greater distances two modules can be configured as a repeater.

Pinout:
- VCC........5V
- A............Non-inverting Receiver Input and No-inverting Driver Output.
- B............Inverting Receiver Input and Inverting Driver Output
- GND.......0V

- R0..........Receiver Output (to Rx pin of microcontroller)
- RE..........Receiver Output Enable (Low to enable)
- DE..........Driver Output Enable (high to enable)
- DI...........Driver Input (to Tx pin of microcontroller)
