MOT-EF02025 L298 Motor Shield SHD-L298N
US$19.53
This Freaduino Compatible Motor Shield (2A) uses L298P chip which allow to drive two 7-12V DC motors with maximum 2A current. This shield can be directly mount onto standard Arduino Duemilanoveand Arduino Mega.  The speed control is achieved through conventional PWM which can be obtained from Arduino's PWM output Pin 5 and 6. The enable/disable function of the motor control is signalled by Arduino Digital Pin 4 and 7. The Motor shield can be powered directly from Arduino or from external power source. It is strongly encouraged to use external power supply to power the motor shield.

DFR0513 PPM 2x3A DC Motor Driver
US$26.25
This motor driver module is a special PPM signal motor controller for Aero modelling remote control. It is designed by DFRobot and it can be controlled by RC transmitter. The driver can convert PPM signal to the motor speed and direction control signal. There are two signal receiving channels (CH1, CH2) and two motor channels (M1, M2) on the board. Each signal input channel uses a standard 50-Hz PPM signal with a duty cycle of 5% to 10%. When the rocker returns to the middle, the motor stops rotating, waggling the rocker up and down (or left and right), and the motor rotates forward or backward.
