Description
Arduino Uno is the basic and most popular version of the whole series. The board containsan ATmega328 microcontroller,equipped with 14 digital inputs/outputs of which 6 can be used as PWM outputs (e.g. for controlling motors) and 6 analogue inputs. The circuit is clocked with a 16 MHz clock signal, has 32 kB of Flash memory and 2 kB of SRAM. This version comes in a larger, decorative box.
This version comes in a large, decorative box with a mini poster inside.
This is an original Arduino product, Botland is anofficial distributor of this company.
Main features
Below we present some features that distinguish Arduino modules from other programmable tiles.
| The name | Description |
|---|---|
|
Installed bootloader |
Thanks to the installed bootloader, the appropriateUSB cable andsoftware from the manufactureris sufficient to program the device. |
|
Arduino Shield |
The layout of connectors enables installation of dedicatedArduino Shieldcovers. |
|
Extracts . digital |
14 digital inputs/outputs enable, among other things, to control LEDs, relays and read button statuses. |
|
Performance Current |
The maximum current capacity of a single output is 40 mA. |
|
Outputs PWM |
6 PWM outputs allow e.g. for motor control and diode brightness adjustment. |
|
Inputs analogue |
6 inputs of the built-in 10-bit analogue-to-digital converter support, among others, sensors with analogue output. |
|
Communication serial |
The device supports popular communication interfaces, among others: UART, I2C and SPI. |
| Special functions | Some pins have special functions, a brief description of which is available in our guide. |
|
Memory Embedded |
The Atmega328 is clocked with a 16 MHz clock signal, has 32 kB of flash memory and 2 kB of SRAM. |
|
Power supply DC connector |
Any power supplyfrom 7V to 12V with 5.5 x 2.1mm DC connector can be used to power Arduino. |
|
Power supply USB port |
The board can be powered from a computer viaa USB cable witha maximum current capacity of 500 mA. Arduino has a system that protects the socket against short circuit and too high current flow. |
|
Connector . ICSP |
The module has ICSP outputs to connect an externalAVR programmer. |
|
Pin IOREF |
The IOREF pin allows for direct access to the voltage with which the I/O outputs work. |
|
Built-in LED |
The connected LED on pin 13 allows debugging of simple programs. |
|
Output 3,3 V |
The built-in voltage regulator enables external devices to be supplied with 3.3 V with current consumption of up to 50 mA. |
|
Microcontroller in THT |
Thanks to the THT threaded case, theAtmega328P microcontrollercan be easily replaced in case of damage. |
|
First start-up In order to make it easier to start working with the module, we have prepared aguidethat covers the installation and first start-up of Arduino environment. |
