Arduino UNO + Prototype Shield+ L293D Motor Drive ShieldMarke: SainSmart Deutschland SKU: 20-011-C42
The SainSmart Uno for Arduino is a
microcontroller board based on the ATmega328. It has 14 digital input/output
pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal
oscillator, a 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
The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega8U2 programmed as a USB-to-serial converter and has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode.
The SainSmart Prototype Shield is a great kit to new Arduino 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. Try any circuit you want to the Arduino. You also can choose to use your own breadboard.
The SainSmart 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.
