Arduino Micro ATmega32U4 is essentially a shrunk-down (1.9″ × 0.7″) version of the Arduino Leonardo: it is a microcontroller board based on the ATmega32U4 running at 16 MHz with 24 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs). This board ships with the male header pins soldered in, as shown in the product picture.

Arduino Pro Mini ATMEGA328P is a 3.3V Arduino (Official Version) running the 8MHz bootloader. Arduino Pro Mini ATMEGA328P comes with connectors so that you can solder connectors or wires with any orientation you need. We recommend the first-time Arduino users start with the Uno R3. It’s a great board that will get you up and be running quickly. The Arduino Pro series is meant for users that understand the limitations of system voltage (3.3V), lack of connectors, and USB off-board.

This L298N Based Motor Driver Module is a high power motor driver perfect for driving DC Motors . H Bridge Driver Module uses the popular L298 motor driver IC and has the onboard 5V regulator which it can supply to an external circuit. It can control up to 4 DC motors, or 2 DC motors with directional and speed control. This Motor Driver is perfect for robotics and mechatronics projects and perfect for controlling motors from microcontrollers, switches, relays, etc. Perfect for driving DC for micro mouse, line-following robots, robot arms, etc. An H-Bridge is a circuit that can drive a current in either polarity and be controlled by Pulse Width Modulation (PWM). Pulse Width Modulation is a means of controlling the duration of an electronic pulse. In motors try to imagine the brush as a water wheel and electrons as the flowing droplets of water.
