The megaRF is a microcontrollerboard based on the ATmega168 and the RFM12 RF module. It is compatible with the Arduino IDE, and has a preloaded arduino bootloader. The RF module uses the 433MHz ism band and can be used for sending data wireless between two or more devices. I wrote a simple arduino library, which you can download at my project page: http://www.centre-of-competence.com/?page_id=104
Controller: ATmega168 – 20AU
Clock Speed: 16MHz
Operating Voltage: 2.7-3.8V
Input Voltage: 3.3V
Radio module: HopeRF RFM12B 433MHz
Size: 29.5mm x 35.8mm

So you do not need an additional Arduino board with this? It will take a sketch written for an Uno? What is the range? Does the 2/4GHz version offer more range or less?

This is an Arduino clone with a rf module. You don't need an additional Arduino board, but you need a USB-serial converter or ISP-programmer for programming. There are a few example sketches in my megaRF library.
The range is much better than the range the 2.4GHz module offers, but it depends on walls, etc. I think 3-4 walls or 100m is the maximum the 433MHz module can do (unstable and with a lot of lost packages). With two 433MHz modules in the same room almost no packages get lost.
