# Electronic Speed Controller Template 8sFo ## Description The electronic speed controller (ESC) is an essential part of an electric propulsion system’s hardware. It acts like the brain of the system by telling the motor how fast to go based on data signals it receives from the throttle controller. For smaller applications like drones and RC vehicles, this controller has the name ‘ESC’, whereas for larger manufacturing applications it may be called an electronic control unit, inverter, or motor controller. #drone #motorController #PCA9685 #controller #motor #esc #referenceDesign #project #EFM8BB21F16G #MPU9250 #template ## Project Details -
