Microcontrollers No operating system, usually single core running Mhz speeds Handles multiprocessing by interrupts Resilient Usually 3.3 or 5V and usually around 1 Amp (or both 3.3 and 5.0V) Usually basic if any Internet connection Open and global innovation Uses serial, IC2, and other well understood hardware communication Huge version exist for large project (i.e. Arduino Mega, drones, quadcopter versions). Applications Motor control, server control, robots, weather stations Examples Arduino, Mico:bit, M0 based controllers, AdaFruit Feather, Tensy, Beaglebon
