Description

This Arduino shield is based on a L298P chip that can drive two DC-motors or one bipolar stepper motor. It also has four connectors for servos and two connectors for I²C. The card is very easy to use with three signals for each motor – speed, direction and break. The card also has two analog outputs that gives out 1.65 Volts per Ampere that the motors use. The break function can be completely deactivated by cutting two thin paths on the back of the circuit board so that these Arduino-pins can be used by other functions. The same goes for the analog signals for measuring the motor current.

The shield uses the following digital connections on the Arduino board:

  1. PWMA – Speed motor A, set using AnalogWrite(3, <0-225>);
  2. BREAKB – Break motor B, set to high to short circuit motor B
  3. BREAKA – Break motor A, set to high to short circuit motor A
  4. PWMB – Speed motor B, set using AnalogWrite(11, <0-255>);
  5. DIRA – Direction motor A, toggle between high and low to change direction of motor A
  6. DIRB – Direction motor B, toggle between high and low to change direction of motor B

In addition the following analog inputs are used:

  1. Current usage motor A (1.65 V/A)
  2. Current usage motor B (1.65 V/A)
