Arduino  board designs use a variety of microprocessors and controllers

A lithium polymer battery, or more correctly lithium-ion polymer battery is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte.

The most common uses of brushless DC motors in industrial engineering are linear motors, servomotors, actuators for industrial robots, extruder drive motors and feed drives for CNC machine tools.

An electronic component is any basic discrete device or physical entity in an electronic system used to affect electrons or their associated fields.
