3 Arduino Mega Via Max485 Communication

Posted by ardnahc pada 21 Oktober, 2013

I’m wiring 3 arduino mega connected via 3 max485 chip. The arduino is using easytransfer library by bill porter. Much thanks to him making 485 communication much much easier. http://www.billporter.info/

Here is the wiring connection of max 485 chip:

pin to

1 RX of each arduino. doesn’t need to be connected for transmitting side of arduino.

2 pin 3 of each max 485 chip

3 pin 2 of each max 485 chip, connected to GND for receiving side, or VCC for transmitting side

4 TX of each arduino. doesn’t need to be connected for receiving side of arduino.

5 VCC (+5V)

6 connected to pin 6 of other max485

7 connected to pin 7 of other max485

8 GND

when transmitting arduino led blinking, the other receiving arduino led are blinking following the transmitting one.
