An ESP32 Breakpout Board with a dual H bridge

This project is for an ESP32 Breakout board that was designed to be the brains of your next robot. The features of this board are;

Can accommodate any ESP32 dev kit that has two rows of up to twenty pins on one inch centers. A place to mount a TB6612FNG dual H bridge DC motor controller daughter board. A two screw terminal block for each motor connection. A two screw terminal block and a set of five header pins for Vin & Gnd Two rows of twenty GPIO breakout pins. Headers for two HC-SR04 Sonar sensors, with voltage dividers on the Echo output. A header for connecting to a tri-color, common…
