CC2538 : Новый SoC от Texas Instrument

Уже давно подумываю о автоматизации некоторых домашних процессов, и просто не смог пройти мимо подобной новости.

В подажу и производство запущена серия чипов

если кратко, то это System-On-Crystal : Cortex-M + ZigBee TRX.  Что открывает безграничные возможности для построения "умного дома".
