3190-ADA H-Bridge Brushed DC Motor Driver DRV8871 Breakout Board For Arduino PWM Control
US$12.51
Two logic inputs control the Hbridge driver, which consists of four N-channel MOSFETs that can control motors bidirectionally with up to 3.6-A peak current. The inputs can be pulsewidth modulated (PWM) to control motor speed, using a choice of current-decay modes. Setting both inputs low enters a low-power sleep mode.

1438-ADA Adafruit Motor/Stepper/Servo Shield for Arduino v2 Kit - v2.3
1438-ADA Adafruit Motor/Stepper/Servo Shield for Arduino v2 Kit - v2.3
US$34.92
Instead of a L293D darlington driver, we now have the TB6612 MOSFET drivers with 1.2A per channel current capability (you can draw up to 3A peak for approx 20ms at a time). It also has much lower voltage drops across the motor so you get more torque out of your batteries, and there are built-in flyback diodes as well. Instead of using a latch and the Arduino's PWM pins, we have a fully-dedicated PWM driver chip onboard. This chip handles all the motor and speed controls over I2C. Only two data pins (SDA & SCL in addition to the power pins GND & 5V) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or shields to the same pins. This also makes it drop-in compatible with any Arduino, such as the Uno, Due, Leonardo and Mega R3.

BOB-09118 Opto-Isolator Breakout
BOB-09118 Opto-Isolator Breakout
US$9.05
This is a board designed for opto-isolation and electrically isolates a controller from the high-power system by use of an opto-isolator IC. This board is helpful for connecting digital systems (like a 5V microcontroller) to a high-voltage or noisy system.
