UNO R3 Development Board with USB cable + L293d Motor Driver for Robotics Projects

Microcontroller !! UNO has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, 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 an AC-to-DC adapter or battery to get started More About Uno Microcontroller Chip - ATmega328P Operating Voltage - 5 V Input Voltage(Recommended) - 7-12V Analog I/O Pins - 6 Digital I/O Pins - 14 (of which 6 provide PWM output) PWM Digital I/O Pins - 6 Clock Speed - 16 MHz Flash Memory - 32 KB (ATmega328P) of which 0.5 KB used by bootloader SRAM - 2 KB (ATmega328P) EEPROM - 1 KB (ATmega328P) DC Current for 3.3V Pin - 50 mA DC Current per I/O Pin - 20 mA On Board LEDs - Yes Operating Temperature (°C) : -10 to 60 Weight (gm) - 25 Length (mm) - 68.6 Width (mm) - 53.4 Height (mm) - 12.5 L293D motor drive for 9v and 12v supply for BO and DC motors.
