{"title":"Arduino Uno DIP Edition","handle":"arduino-uno-dip-edition","url":"/products/arduino-uno-dip-edition","description":"This is the DIP-package version of the classic Uno, built around the ATmega328 microcontroller. It brings out 20 digital input/output lines, including PWM-capable pins and analogue inputs, and includes the essentials on board: a 16 MHz resonator, USB connection, power jack, ICSP header and reset button.The removable dual-inline-package AVR can be taken out of its socket, which is the main difference from the functionally identical SMD edition. This older Uno revision has since been replaced by the Arduino Uno R3, but it remains a familiar platform for learning embedded electronics and building shield-based projects.Connect it to a computer over USB to program it with the Arduino software, or power it from a suitable AC-to-DC adaptor or battery. The ATmega8U2 handles USB-to-serial conversion, and the ATmega328 comes with a preburned bootloader so you can upload sketches without an external programmer.The Uno ecosystem includes a large support community, extensive software libraries and a wide range of hardware add-on shields for wireless, robotics, sensing and introductory electronics projects.Features:Removable AVR: Uses a removable dual-inline-package (DIP) ATmega328 microcontroller.SMD edition compatibility: A functionally identical SMD edition is available; the only difference is the microcontroller package.Digital I/O: 20 digital input/output pins are available.PWM: 6 digital pins can be used as PWM outputs.Analogue inputs: 6 pins can be used as analogue inputs.On-board essentials: Includes a 16 MHz resonator, USB connection, power jack, ICSP header and reset button.USB-to-serial: Uses an ATmega8U2 programmed as a USB-to-serial converter instead of an FTDI USB-to-serial driver chip.Reprogrammable USB interface: The ATmega8U2 has its own USB bootloader for advanced users who want to reprogram it.Arduino ecosystem: Supported by Arduino libraries, tutorials, community resources and hardware add-on shields.USB power: Can be powered via the USB connection.External power: Can be powered from an AC-to-DC adaptor or battery.VIN: Provides access to the input voltage when the board is using an external power source, and can also be used to supply voltage.5V: Provides the regulated power supply used to power the microcontroller and other board components.3V3: Provides a 3.3 volt supply generated by the on-board regulator.GND: Ground pins are provided on the power connector.Serial: Digital pins 0 (RX) and 1 (TX) are used for TTL serial receive and transmit.External interrupts: Digital pins 2 and 3 can trigger interrupts on a low value, rising or falling edge, or change in value.PWM pins: Pins 3, 5, 6, 9, 10 and 11 provide 8-bit PWM output with analogWrite().SPI: Pins 10 (SS), 11 (MOSI), 12 (MISO) and 13 (SCK) support SPI communication using the SPI library.Built-in LED: Digital pin 13 is connected to an on-board LED.I2C: Analogue pins 4 (SDA) and 5 (SCL) support I2C (TWI) communication using the Wire library.AREF: Provides a reference voltage input for the analogue inputs.Reset: The reset line can be brought LOW to reset the microcontroller, useful for shields that block the on-board reset button.Virtual COM port: USB serial appears as a virtual COM port to computer software.Serial monitor: The Arduino software includes a serial monitor for sending simple text data to and from the board.RX/TX indicators: RX and TX LEDs flash when data is transmitted via the USB-to-serial chip and USB connection.SoftwareSerial: A SoftwareSerial library allows serial communication on any of the Uno’s digital pins.Wire library: The Arduino software includes the Wire library to simplify use of the I2C bus.SPI library: SPI communication is supported through the SPI library.Arduino IDE programming: Programmed with the Arduino software by selecting Arduino Uno from the Tools > Board menu.Preburned bootloader: Upload new code without using an external hardware programmer.ICSP programming: The bootloader can be bypassed by programming through the ICSP header.DFU firmware loading: The ATmega8U2 DFU bootloader can be activated for loading new firmware.Automatic reset: Software on a connected computer can reset the board before uploading code.Reset enable trace: The RESET-EN trace can be cut to disable auto-reset and soldered together to re-enable it.USB overcurrent protection: A resettable polyfuse helps protect the computer’s USB ports from shorts and overcurrent.Mounting: Four screw holes allow the board to be attached to a surface or case.Specifications:Microcontroller: ATmega328Operating voltage: 5 VInput voltage (recommended): 7-12 VDigital I/O pins: 20 (of which 6 provide PWM output)Analog input pins: 6*DC current per I/O pin: 40 mADC current for 3.3V pin: 50 mAFlash memory: 32 KB (ATmega328) of which 0.5 KB used by bootloaderSRAM: 2 KB (ATmega328)EEPROM: 1 KB (ATmega328)Clock speed: 16 MHzAnalog input note: The Arduino Uno has 20 total available I/O lines;
