YFRobot L298P Motor Shield
This board is electrically the same, though a different layout than the Arduino motor shield. Often cheaper. Supports 2A per channel, but can deliver realistically 1.3 or maybe 1.5 Amps with an added heatsink and cooling fan. Do NOT confuse this with the DFRobot Motor Shield, which is not plug and play!

Install the YFRobot Motor Shield (same as Deek-Robot)
Remember to select YFROBOT_MOTOR_SHIELD in your config.h file or from the motor board dropdown if using EX-Installer
Pinout for reference:
Note
This configuration uses the normal accuracy waveform to avoid having to use jumpers. To use the high-accuracy waveform, you would need to use pins 3 and 11 in your motor board definition in config.h and jumper them to D5 and D6 on the shield. For information about high-accuracy mode, See:
