Manufacturer: Arduino


Arduino Uno is the main and, at the same time, the most popular edition of the entire series. The Board contains an ATmega328 microcontroller, equipped with 14 digital I/o of which 6 can be used as PWM outputs (e.g. for motor control), and 6 analog inputs. The system works with the signal ticking with the frequency of 16 MHz and has 32 KB Flash memory and 2 KB RAM SRAM.


The subject of the sale is the original product of Arduino Uno, Botland is the official distributor of this company.

Key features

Below are a few features that distinguish modules Arduino Uno compared to other programmable tiles.


Name Description



Thanks to installed bootloader, to programme the device, the appropriate USB cable and software from manufacturer's website is enough .



The distribution of connectors allows the installation of special plates, so-called Arduino Shield.



14 digital inputs/outputs allows, in particular, control of LEDs, relays and reading the buttons' states.

Efficiency of


The maximum power load for a single output is 40 mA.



6 PWM outputs allow e. g. motor control and brightness control of the LEDs.



6 inputs of built-in analog-digital converter box with a resolution of 10-bit support, in particular, sensors with analog output.



The device supports popular network interfaces, including UART, I2C and SPI.
Special functions Some of the pins have special functions and their brief description is available in our guide.



Atmega328 system with a clock signal with a frequency of 16 MHz, has 32K Flash memory, 1 KB EEPROM and 2 KB of RAM SRAM.


DC connector

To power the Arduino, you can use any power source with a voltage from 7 V to 12 V with DC connector 5.5 x 2.1 mm.


USB port

The tile can be powered from a computer via USB cable, bearing in mind that the maximum power load for the USB port is 500 mA. Arduino has a system that protects the socket from short-circuit and the flow of too large current.



The module has ICSP outputs for connecting an external AVR programmer.



The IOREF Pin provides direct access to the volatge with which I/O outputs work.



The connected led on pine 13 allows debugging of simple programs.


3.3 V

Built-in voltage regulator provides power to external devices with the voltage of 3.3 V with current consumption of 50 mA.


in THT

Thanks to the use of THT case, in case of damaging the main microcontroller Atmega328P you can easily replace it.


First run

To help you get started with the module, we have prepared a tutorial that concerns the installation and first run of the Arduino environment.

Question: Good day, does this product have a replaceable microcontroller as shown in the picture? Greetings Daniel
Answer: Yes, the module has a replaceable microcontroller.


Question: Hello, does the arduino uno kit include a board stand? USB cable can be A-B printer cable of course?

It comes with a plastic pad.

USB A-B cable, something like this:
is also very often used in printers.



Question: Good morning I have a question if the kit includes a cable to connect the board to the computer
Answer: Unfortunately, the cable is not included in the set, it can be purchased separately:

The Arduino UNO R3 board is an excellent platform for learning electronics, programming simple microcontrollers, and building your own programmable projects using the C++ language. Some time ago, I became interested in Arduino due to having my own mechanical-electronic workshop, and now I already have two Arduino boards, one of which is used as a control for the CNC milling machine I built earlier, and now I have the Arduino UNO R3, which I also purchased at Botland. Both work excellently, they have the advantage of being easy to use by connecting via USB to a computer or laptop after installing the programming environment.👍️
