RioRand Sensor Shield V5 + Mega2560 + 4wd Mobile Platform Silver + Dual H Bridge Stepper Motor Driver + Hc-sr04, Ultrasonic Distance Sensor for Arduino UNO Mega R3 Mega2560 Duemilanove Nano Robot

The RioRand Sensor Shield V5 has the COM and I2C (IIC) ports separated,so that both ports can be utilized at the same time to increase the possibilities of use.
The RioRand MEGA 2560 Board is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.
This RioRand 4WD Drive Aluminum Mobile Robot Platform can hold many controllers, drivers, sensors and RF modules etc.
RioRand Dual H Bridge Stepper Motor Driver
* Driver: L298N Dual H Bridge DC Motor Driver IC
* Drive Part of the Peak Current: 2A
* Logic Part of the Operating Current: 0 ~ 36mA
* Maximum Power Consumption: 20W ( at 75 deg C)
HC-SR04, Ultrasonic Distance Sensor: There are 4 pins out of the module : VCC , Trig, Echo, GND . So it's a very easy interface for controller to use it ranging. The all process is : pull the Trig pin to high level for more than 10us impulse , the module start ranging ; finish ranging .
