1. INTRODUCTION
SHIELD-2AMOTOR is an Arduino shield for controlling dual DC motor up to 2A for each channel. It is compatible with Arduino Uno, Arduino Leonardo, Arduino Mega, Arduino Due and possibly other pin compatible main boards. SHIELD-2AMOTOR uses L298P SMD IC and support for both signed magnitude and locked anti-phase. SHIELD-2AMOTOR shield has stackable side headers which allows for more Arduino shields to be stacked on top of it.
SHIELD-2AMOTOR come with this features:
● Bi-directional control for 2 brushed DC motor.
● Support motor voltage ranges from 5V to 26V.
● Maximum current up to 2A per channel.
● 3.3V and 5V logic level input.
● Stackable I/O header pin.
● Selectable pins for Signed Magnitude and Locked Anti-Phase.
● Test switch for both channel.
● External voltage polarity protector.

Reset button
User can press this button to restart Arduino program.
Motor connectors
Connect DC motor here.
External power (PWRIN) connector
Connect external power source here.
PWR LED
Motor power indicator.
Power source selection.
User can choose power source either from external (PWRIN) or internal (VIN).
External power (PWRIN) reverse polarity protection circuit.
In case user wrongly connect the external power source polarity, this circuit will protect the shield from broken.
L298P driver motor IC.
SHIELD-2AMOTOR uses L298P driver motor IC.
Motor control mode selection.
User can choose motor control mode either Signed Magnitude or Locked Anti-Phase .
Test switch.
When button A is pressed, current flows from output A to B and motor will turn CW (or
CCW depending on the connection).
When button B is pressed, current flows from output B to A and motor will turn CCW (or
CW depending on the connection).
LSS05 connector.
LSS05 can connect directly to this shield and can be interfaced with Arduino.
Arduino pinout.
Other Arduino shield can be stacked on top of this shield.

6. HARDWARE
This section shows the example of using SHIELD-2AMOTOR with Arduino Uno as the main controller to control dual brush DC motor. However, other Arduino main board controller can be used ( Leonardo , Mega , Due ).

Figure above shows that SHIELD-2AMOTOR is stacked on the Arduino UNO.
Move 4 mini jumpers to Signed Magnitude or Locked Anti-Phase. 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 PWRIN terminal.
