There are many ways to drive the motor. Our robot uses the most commonly used L298P solution.
L298P is an excellent high-power motor driver IC produced by STMicroelectronics. It can directly drive DC motors, two-phase and four-phase stepping motors. The driving current up to 2A, and output terminal of motor adopts eight high-speed Schottky diodes as protection.
We have designed the motor driver shield based on the L298P circuit.
The stackable design can make it be plugged directly into the Arduino, reducing the technical difficulty of using and driving the motor.
Direct stack the motor driver shield onto UNO R3 board, after the BAT is powered on, press the POWER button, to supply the power for both motor driver shield and UNO R3 board.
For simple wiring, the motor driver shield comes with anti-reverse PH2.0- (2P/3P/4P/5P) interfaces.
When connecting the motor, power supply and sensor modules, you just need to plug in directly.
The Bluetooth interface on the motor driver shield is fully compatible with Bluetooth module. When connecting, just plug Bluetooth module into the corresponding interface.
At the same time, the motor drive shield has brought out extra digital and analog ports in 2.54mm pin headers, so that you can continue to add other sensors for experiments extension.
The motor drive shield can access 4 DC motors. The motor connector A and A1, connector B and B1 are separately in parallel, with the same motion rule.
The shield comes with 4 fixing holes of 3mm, easy to mount on other devices.
