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, 5 of which can be used as outputs PWM (e. g. for motor control), and 6 analog inputs. The system works has clock signal frequency of 20 MHz, has 48 KB Flash program memory, 6KB RAM SRAM, and a 256B 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.
- 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.
- Current: The maximum load current for one I/O is 20mA (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.
- Built-in memory: System Atmega4809 has frequency signal with a frequency of 20 MHz and has 48 KB Flash memory, 256B 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 2.1mm.
- 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 3.3V with current consumption of 50mA.
