These wireless modules use SPI to communicate with an MCU so it will work with everything that supports SPI. Since I'm using xmega (arduino's bigger brother MCU), it should work perfectly with an arduino (except that most Arduino boards are 5V even though the AVR chip itself supports down to 2.7V). The module only works with 1.9V to 3.3V so you will need a level converter.
It does not support any wireless communication protocol though, that you would have to implement yourself. But the programming is fairly straight forward (once you read the datasheet).
I got it from these place
Bought bulk then (80 modules) since shipping is kinda expensive. I've already used up half of it for some various projects (with AVR, mbed, pandaboards, custom boards, etc).
I believe the ebay popular nFR240+ is using the same chip as these modules.
