Here is the L293D motor driver, which performs all tasks performed by an IC. It is a 2-motor controlled double-layer PCB design of the L293D motor driver IC. Here I used Transistors and flysack diodes ...

Four N20 motors power the robot, with movement controlled by the ESP8266 through an L293D motor driver IC. The custom PCB is designed to incorporate critical features in a small form factor, including ...

The tiny CNC plotter uses an Arduino Nano and two L293D ICs mounted to a custom PCB. Which have been translated into the proper format via Inkscape and Processing for your convenience.
