RS485 Shield for Arduino
renedyhr 2018-09-04 02:19:07 5241 Views4 Replies As I understand the things, the Arduino doesn't have RS485 built in.
I have one of these: https://goo.gl/PTaKo5 - a RS485 relay.
But I can't quite get it to work with the shield I bought.
Will the board or the Arduino itself be able to send commands through RS485 to the relay?
An example of the command: "01 06 00 01 01 00 D9 9A".
Or do I need a completely other board?

But I couldn't get the confirmation on that it can be used.
And will it be possible to change the pin from 0 and 1, since that I'm using those for usb to pc. renedyhr
That's the one that I have.robert.chen wrote: ↑Tue Sep 04, 2018 10:29 amHave you consider to use the RS485 shield? https://www.dfrobot.com/product-1024.html

Will it not be possible to use the Arduino in some way with either the board I got or built in the Arduino?

If you want to control the relay by RS485 communication protocol.You should use the STMicroelectronics 32bits series developments board, It supports RS485.Hope help you. makermuyi
