SmartElex L298N Dual Channel Motor Driver with Onboard Arduino Uno

This board collapses two separate purchases into one: an Arduino Uno and an L298N motor driver, stacked onto a single PCB sized for a small robot chassis. For anyone building a two-wheel robot, that means one board to mount, one set of headers to wire, and no jumper mess between a driver shield and a separate microcontroller.

The L298N side drives two DC motors independently at up to 2A per channel across the usual 5V-35V range, while the onboard ATmega328P runs the same Arduino sketches as a standalone Uno - existing motor-control code ports over directly. Extra headers support servo motors and line sensors, which covers the two most common additions to a beginner robot build: a steering or gripper servo, and IR line sensors for a line-follower.

Aimed squarely at line-follower robots, obstacle-avoidance rovers and other small wheeled-robot projects where reducing board count and wiring complexity is worth more than the flexibility of separate components.
