STR9-comStick Development Kit for STR91x Microcontrollers with Free TCP/IP Stack and GNU Compiler - STMicroelectronics

STMicroelectronics announced the STR9-comStick, a low-cost USB stick development kit for STR91x 32-bit microcontroller family. The ST’s STR9x microcontrollers, based on ARM966E core is particularly suited to networked embedded applications. The comStick is an easy-to-use entry-level tool that simplifies the evaluation and development of networked applications taking advantage of the computing power and connectivity features of the STR91xF microcontrollers.
