SainSmart Leonardo R3 Improved Version Board

The SainSmart Leonardo is a microcontroller board based on the ATmega32u4 . It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

SainSmart Motor Driver Shield:

• L293D is a monolithic integrated, high voltage, high current, 4-channel driver.

• Basically this means using this chip you can use DC motors and power supplies of up to 36 Volts, thats some pretty big motors and the chip can supply a maximum current of 600mA per channel, the L293D chip is also what’s known as a type of H-Bridge.

• The H-Bridge is typically an electrical circuit that enables a voltage to be applied across a load in either direction to an output, e.g. motor.

• 2 interface for 5V Servo connected to the Arduino's high-resolution dedicated timer - no jitter.

• Can drive 4 DC motors or 2 stepper motors or 2 Servo.

• Up to 4 bi-directional DC motors with individual 8-bit speed selection.

• Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil or interleaved stepping.

• 4 H-Bridges: per bridge provides 0.6A (1.2A peak current) with thermal protection, can run motors on 4.5V to 36V DC.

• Pull down resistors keep motors disabled during power-up.

• reset button.

• 2 external terminal power interface, for seperate logic/motor supplies.

• Tested compatible for Arduino Mega, Diecimila & Duemilanove.

• Size:6.8cm x 5.5cm x 2cm - 2.68inch x 2.17inch x 0.79inch.

SainSmart Prototype Shield:
It is a great kit to new users and geeks who have sparkling ideas. You can choose to do soldering in the soldering area. You can also make good use of the mini breadboard which can save your time of soldering, to try any circuit you want to the Arduino. You also can choose to use your own breadboard.

 Mini Breadboard:

•    170 tie points.
•    Self-adhesive backing to stick on the  Protoytpe Shield
•    Strong
•    Measures 1.7"x1.3"
