We do not store credit card details.
TheArduino Uno Rev3 SMD / A000073 is a complete analog of the Arduino Uno Rev3 / A000066 board, but with a surface mount Microchip ATmega328P SMD microcontroller chip. It also has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), USB connection, power connector, ICSP connector, and reset button. We recommend buying the original arduino uno r3 in Ukraine to anyone who is interested in programming. Unlike its predecessor, the Arduino Uno, this product uses a modified ATmega328 microcontroller, which is enclosed in a more compact package and has better power consumption.
The name "Uno" means "one" in Italian and was chosen to commemorate the release of the first version of the Arduino software (IDE) 1.0. The Uno board and version 1.0 of the Arduino software (IDE) were the reference versions of the Arduino, which have now evolved to newer versions.
We recommend buying the Arduino uno r3 starter kit as an introduction to the most popular platform. Using this product, you will get an idea of the product's capabilities, which will further allow you to create the most functional and multi-level gadgets based on it. It is advisable to buy Arduino uno r3 in Kyiv in a complete set, including, in addition to the board itself, a special 12-volt power supply, as well as a USB cable for communication and programming. Please note that a simplified version of the C++ language is used to create programs. At the choice of the developer-programmer, you can use both a specially created free Arduino IDE software shell and specialized C and C ++ tools.
The Arduino uno r3 starter kit, which can be purchased at an affordable price by every visitor to our website, has the following main features:
- 14 digital connectors and ports,
- 6 inputs for analog devices,
- a 16 MHz central processor,
- USB port for communication and programming,
- power supply connector,
- ICSP type connector,
- reset button.
To start using the Arduino uno r3 rev3, you just need to connect the microcontroller with a USB cable to a personal computer or laptop, and then start programming.
