The RADiuS Shield is Open Hardware...an easy to use wireless solution for Arduino compatible microcontrollers. Well... really, it will work with just about anything that can talk RS232.

So... here you go! You'll need Eagle to view / edit the attached file ( Mac, Windows, Linux versions available ). Ordering PCBs is really easy... just a few clicks and you're good to go.

Here's the bill of materials (BOM) to populate the shield. If you have any questions - let me know!
