DescriptionThe Arduino Uno is a microcontroller board with 14 digital input/output pins (6 of which can produce PWM), 6 analogue inputs, and a USB connection. It is compatible with the original UNO R3 and can be directly replaced. It uses the Atmega16U2 chip, which is programmed as a USB-to-serial converter, and has a stronger RESET circuit. Additionally, the board has two new pins, the IOREF pins, which allow the shields to adapt to the voltage provided by the board.SPECIFICATIONSOperating Voltage: 5VInput Voltage (recommended): 7-12VInput Voltage (limits): 6-20VDigital I/O Pins: 14 (of which 6 provide PWM output)Analog Input Pins: 6DC Current per I/O Pin: 40 mADC Current for 3.3V Pin: 50 mAFlash Memory: 32 KB (ATmega328) of which 0.5 KB is used by the bootloaderSRAM: 2 KB (ATmega328)EEPROM: 1 KB (ATmega328)Clock Speed: 16 MHzPINOUTDOCUMENTTutorialDOWNLOADSDownload Arduino IDESHIPPING LIST1 x Arduino UNO Compatible board1 x USB B type USB cable (1m)
