Texas Instruments, Inc. announced its eZ430-RF2500 tool for designing embedded systems that combines ultra-low-power MSP430 microcontrollers (MCU) with wireless communications. The development tool, packaged in a USB stick form factor, offers two radio frequency-enabled microcontroller target boards and a PC debugging interface that can be used to develop stand-alone wireless projects. The tool enables developers to build low-power wireless systems for sensing and metering, home security and automation, and medical applications. It provides the hardware and software needed to program the MSP430 MCU and the low-power RF 2.4 GHz transceiver on the postage stamp-sized target board. The tool provides a complete system for writing code as well as for operating and testing the application in the field.
