The wake-up feature of the internal oscillator and USARTs (without data loss) in combination with tiny 3x3 QFN package makes the ATtiny441/841 devices attractive. 4/8 KBytes of internal FLASH memory could be good enough for small applications. Atmel thinks these devices are ideal for cost-effective consumer applications such as computer accessories, thermostats, personal health accessories etc. For what kind of applications you would use these controllers?
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
