Arduino Uno R3 Microcontroller

Описание

Product description 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.  Technical Specifications  Microcontroller: ATmega328  Operating Voltage: 5V Supply Voltage (recommended): 7 to 12V  Maximum supply voltage (not recommended): 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 (ATmega328)  EEPROM: 1 KB (ATmega328)  Clock Speed: 16 MHz
