Arduino Uno R3 Compatible Board (With Cable – DIP Version)

This board is fully compatible with the Arduino Uno R3. It has a DIP version of the ATmega328p-PU MCU, which enables the user to remove or replace the main MCU if needed. The Arduino Uno has 32KB Flash, 2 KB SRAM and 1 KB EEPROM. It has 20 Digital I/O pins. Out of which 6 pins support PWM output. And out of which 6pins can also function as Analog Inputs. All the GPIOs support Pin change interrupt, where as digital interrupt is available only on Pin No 2 and 3.

The board has 1 x USART, 1 x SPI, and 1 x I2C peripherals. It has USB Connector and a power jack. It can source power via USB or via a Power Jack. The board operates on 5V, where as the input voltage is 7V to 12V. It has an onboard voltage regulator. It also has output for 3.3V. Each of the pins have current sink capability of 40 mA. The 3.3V output has current capability of 50 mA. It works on 16Mhz crystal frequency.

The board can be programmed via USB using the Arduino IDE. It can be also programmed via dedicated pins, but a special Programmer like Atmel ICE is needed to program through those pins. The Arduino IDE has vast library for including or attaching various peripherals to the board.
