The D1 Mini offers three motor shields. They all control two motors, but use different motor driver chips. Although they have slightly different voltage and current properties, they don't strike me as dramatically different. Can anyone advise me on the practical differences between these three shields and what criteria would guide one's choice between these shields for a given application? Are they really offering three different devices just to support some subtle voltage/current differences?
