rs-485

For a device thats rs-485 to communicate with a moteino do I need a seperate module or is there code that could do it?
Thanks

At the least you will need another module, that does the TTL to rs-485 buffering.

Is there a module that you would recommend? I see a lot on ebay/amazon. Do they generally require code or you just connect 1 side to the ttl and 1 side to rs-485?
Thanks

The descriptions give more details how you'd connect/use them with a 3.3v system.
