Now you can run the Arduino IDE and communicate with the board.Select the newly added COM port number which can be found in the Device Manager Panel.Install the downloaded USB Driver, then plug UNO development board, the driver will automatically install.Use only if you are having problems USB Driver Install Steps: Flash Memory: 32 KB (ATmega328P) of which 0.5 KB used by bootloader.Digital I/O Pins: 14 (of which 6 provide PWM output).This upgraded model is completely compatible with original Arduino UNO.Documents: Schematic Eagle Files Product Page Arduino IDE. Upgraded revision featuring stronger reset circuit and CH431A USB Features: 14 Digital I/O Pins (6 PWM outputs) 6 Analog Inputs 32k Flash Memory 16Mhz Clock Speed. 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. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analogue inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. The Arduino UNO is a microcontroller board based on the ATmega328. 6 dB Fixed Attenuator, N Male to N Female.10 dB Fixed Attenuator, BNC Male to BNC Female.36 way Single row header (2.54mm pitch).Inductive Proximity Limit Sensor/Switch.Arduino Nano, Arduino Pro Mini, Arduino Mega, Arduino Due, Arduino MKR1000 Wi-Fi Board, Arduino Leonardo. Capacitive Proximity Limit Sensor/Switch Note: Complete technical information can be found in the Arduino UNO Datasheet, linked at the bottom of this page.
