The Arduino family

Arduino Uno with Openlabs board

(This is very much work in progress, hopefully it will work in the end)

• Arduino Uno with Atmega328P-PU.
• Openlabs Radio board with AT86RF233.

Arduino Uno with Openlabs "Raspberry Pi 802.15.4 radio" over SPI.

This is an addon module for the Raspberry Pi. Intended for use with the lowpan userspace tools and the wpan-next Linux kernel, it adds support for 6LoWPAN over 802.15.4 (2.4GHz) to the Raspberry Pi.

The module comprises a chip antenna, crystal oscillator, and an Atmel AT86RF233, which is a 2.4GHz SPI-to-antenna transceiver IC with 802.15.4 hardware assist. This is therefore an SPI-to-airwaves 802.15.4 solution.

The header pins are matched to pins 15-26 of the RPi P1 header, but this design is otherwise not RPi-specific. It would not be wrong to call this a simple AT86RF233 breakout board with an antenna and crystal.
