“Motor voltage: 24 VDC, 38 VDC (E-type). In my case, I used 12VDC power supply to the motor because this voltage level is compatible with L293D Motor Arduino Shield.

This shield could be a good alternative to hobby RC controllers for robots that need a customizable open-source motor controller. The PCB design and source code are available on GitHub .

It uses an Arduino and a motor shield for locomotion, with commands pushed to it via USB. ... [Chris] is using the Adafruit motor driver shield. It uses L293D H-bridge chips, ...

The High Power H-Bridge Motor Shield for Arduino is equipped with built-in current sensing utilizing the ACS712, and is capable of driving any DC motor up to 15Amp.
