We stacked two Adafruit Motor Shields V2 for Arduiono Mega to run 3 1.8-stepper motors (12 V) and controlled movement with buttons. We are directly powering one shield with a power supply of 12 V and over 1.2 A of current. The motor connected to the shield that is directly supplied with 12 V (bottom…
