panStamps are small open source wireless modules designed to add RF connectivity to sensors, MCUs and similar projects. The crew at panStamp is in the process of developing a new module based on the TI CC430F5137 SOC. Programming will be via the Arduino IDE, facilitated through a port being developed by the open sourceEnergia project.
Commercial release of this new line of panStamps is planned for September-October. For more info visit PanStamp.
