Special Features
Arduino UNO is an Arduino development board based on ATmega328P. It has 14 digital input/output pins (6 of which can be used for PWM output), 6 analog input pins, a 16MHz crystal oscillator, a USB interface, a DC interface, an ICSP interface, and a reset button. It contains everything you need for a microcontroller, and you can drive it simply by connecting it to a USB port on your computer, using an AC-DC adapter, or using a battery.
Operating voltage 5V. Input voltage (recommended) 7-12V. Input voltage (limit) 6-20V. DC output capability per VO: 20 mA. 3.3V port output capability 50 mA.
Digital VO pin: 14. PWM channel: 6. Analog input Channel (ADC): 6. On-board LED pin: 13.
Flash 32KB(where the boot program uses 0.5KB). SRAM: 2KB. EEPROM: 1KB. Clock speed: 16 MHz.
Arduino UNO is the number development board of Arduino series, Arduino IDE1.0 is the first official version of Arduino IDE, Arduino UNO hardware and Arduino IDE software establish a set of Arduino development standards, and then Arduino; Development boards and derivative products are built on this standard.
