Hello!
Sorry for bad english, but i have some troubles with mega sensor shield v2.1 and urn04 v2.0 connection. I just dont know how to do it. Is it possible? I really need help!!!!
2012-06-20 21:51:00 I have made a connection diagram for Arduino using a MAX485 IC. This connection diagram is based on the IO Exapsion shield schematic.

I'm sorry about my last response. I was mistaken the SPI port is only to upload new firmware. This sensor only works by using RS-485 protocol.


So you can use our Arduino[url=https://www.dfrobot.com/index.php?route=product/product&filter_name=dfr0088&product_id=264] IO Expansion Shield[/url]. Or a MAX485 chip.

You should be able to connect it to the MEGA Using the SPI pins. I will make a connection diagram for you and post it soon.
