Product User’s Manual – 2A Motor Driver Shield
Figure above shows that the SHIELD2AMOTOR is stacked on the Arduino UNO. Please ensure
that the pins alignment is correct.
Select pin mode (4 pins) to be Signed Magnitude or Locked AntiPhase. The default setting is
Signed Magnitude. Make sure correct power source is selected (VIN or PWRIN). VIN will
connect to the Arduino power source, while PWRIN needs external power source connected to the
