Description
Popular version of Arduino Uno board with built-in microcontroller AVR ATmega4809and system U-block W102 for communication with the wi-fi network. ATmage4809 was equipped with14 digital input/outputs, 5of which can be used as outputs PWM (e. g. for motor control), and6 analog inputs. The system works has clock signal frequency of20 MHz, has48 KB Flash program memory,6 KB RAM SRAM, and a 256 B EEPROM. Tile is equipped with a system IMU (Inertial Measurement Unit) and a cryptographic moduleECC608.
Key features
Below are a few features that distinguish modules Arduino compared from the other programmable tiles.
NAME DESCRIPTION
Installed
bootloader
Thanks to bootloader, for programming the device the only necessities are appropriate USB cable and software from manufacturer's website.
Wi-Fi Module
Built-in module U-block W102 allows you to access wi-fi and that allows you to create a network of IoT (Internet of Things).
Digital I/O
14 digital inputs/outputs allow, in particular, to control the LEDs, relays and reading the buttons' states.
Efficiency
current
The maximum load current for one I/O is 20 mA (50 mA output 3.3 V).
Output
PWM
5 outputs PWM allow, for example, to control the motors and brightness of the LEDs.
Analog inputs
6 inputs of built-in digital-analog converter with a resolution of 10-bit, support, in particular, sensors with analog output.
Serial communication
The device supports popular communication interfaces, including UART, I2C and SPI.
Special functions
Some of the pins have special functions that a brief description is available inour guide.
Built-in memory
System Atmega4809 has frequency signal with a frequency of 20 MHz and has 48 KB Flash memory, 256 B EEPROM and 6 KB of RAM SRAM.
Supply
DC connector
To power the Arduino, you can use any power supply with voltage up to 12V with DC connector 5.5 x 2.1 mm.
Supply
USB port
The tile can be powered from a computer via USB cable, bearing in mind that the maximum load current for the USB port is 500 mA. Arduino has a system that protects the socket from short-circuit and the flow of too high current.
Connector
ICSP
The module has ICSP I/O for connecting an external AVR programmer.
Pin
IOREF
The IOREF Pin provides direct access to the voltage with which output I/O work.
Built-in
led
The connected led on pin 25 allows debugging simple programs.
Output
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.
