Arduino Uno Board


The Arduino Uno 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 get started. Specification: Arduino type: Uno, Microcontroller: ATmega328, Operating voltage:5V, Input voltage range nominal: 7-12V, Maximum supply voltage: 20V, Digital I/O pins: 14 (of which 6 provide PWM output), Analog input pins: 6, DC Current per I/O pin: 40 mA, DC Current for 3.3V pin: 50 mA, Flash memory: 32 KB (ATmega328) of which 0.5 KB used by bootloader, SRAM: 2 KB, EEPROM: 1 KB, Clock speed: 16 MHz, USB Connector type: B Male
