I can recommend Openlabs RaspberryPi 802.15.4 radio [0]. It's for 2,4GHz, uses Atmel radio, and is very reasonably priced. Delivery by USPS took 12 days to Poland which is not bad at all for 8$. > If yes, does this hardware work with a standard Linux vanilla kernel and which > version is required?

Up to my knowledge, the development is currently happening in bluetooth-next branch [1]. Previously it happened in linux-wpan-next, and net-next. There is a tutorial on Openlabs [3] which is still mostly correct. I also started fixing old RPL implementation from Joao Pedro Taveira to work with new branch. Results are promising, prefixes are distributed, but multihop doesn't work yet [3]. > And has anyone ever tried to connect such a device to a RIOT driven device? I tried it with old Atmel Raven motes running Contiki. I don't have any ARM board yet for RIOT to check. To sum up: this option works and it's cheap to try - if you have a RaspberryPi, you just need to spend 18$ to start developing.
