You will not have access to the full suite of features the TReX Jr provides if you do not make use of the serial interface

Pololu Dual G2 High-Power Motor Driver 24v14 Shield for Arduino POL_P-Star Programmable Controllers or it can be setThis shield makes it easy to control two high power DC motors with your Arduino or Arduino compatible board. Its twin discrete MOSFET H bridges support a wide 6. 5 V to 40 V operating range and are efficient enough to deliver a continuous 14 A without a heat sink. The drivers offer basic current sensing and current limiting functionality, and they accept ultrasonic PWM frequencies for quieter operation. The Arduino pin mappings can all be customized
