3d view of the RFM12USB SMD Version
The circuit of the rfm12usb

The RFM12USB consists of an AVR micro controller (Atmega8) paired with a rfm12 transceiver module. This little device allows interfacing your micro controller projects with your computer.

Sourcecode[Bearbeiten | Quelltext bearbeiten]

The source code can be obtained from here. The directory "firmware" contains (who'd have guessed) ... the firmware. Furthermore you'll find several useful examples of how to interface the device from the pc side in the host directory.

RFM12USB SMD Version[Bearbeiten | Quelltext bearbeiten]

If you don't like DIL soldering, there's a SMD Version of the rfm12usb available. You can find all necessary files here. The Layouts have been designed with kicad.

The svn folder also contains 3d models for the rfm12 module (rfm12.wrl) along with the original "source" for the model (rfm12.wings), which can be opened and edited with wings3d.
