Description
Yun is a combination of Arduino Leonardo and AtherosAR9331controller with WiFisupport. The board contains an ATmega32u4 microcontroller equipped with 20 digital inputs/outputs, 7 of which can be used as PWM outputs (e.g. for controlling motors) and 12 as analogue inputs. The board is clocked with a 16 MHz clock signal, has 32 kB of Flash memory and 2.5 kB of SRAM memory.
|
Thanks to using AVR chip together with Bridge library available from Arduino IDE environment, Arduino Yun can easily, wirelessly, through WiFi network, program, configure or change and read output states. After connecting the power supply (5 V througha power supply unitwith micro USB connector), the module is visible on the PC as a WiFi network called Arduino Yun. This version of Arduino Yun has PoE (Power Over Ethernet) module, which allows to power the board from Ethernet network. |
The original Arduino product is sold, 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 appropriatemicroUSB cable andsoftware from the manufactureris sufficient to program the device. |
|
Connection WiFi |
Arduino Yun can be easily programmed, configured or changed and read output states wirelessly, via WiFi network. |
|
Ethernet microSD |
This version has an Ethernet controller with RJ45 connector and PoE power supply and a microSD memory card reader. |
|
Arduino Shield |
The layout of connectors enables installation of dedicatedArduino Shieldcovers. |
|
Extracts . digital |
20 digital inputs/outputs enable, among others, to control LEDs, relays and read button states. |
|
Performance Current |
The maximum current capacity of a single output is 40 mA. |
|
Outputs PWM |
7 PWM outputs allow e.g. for motor control and diode brightness adjustment. |
|
Inputs analogue |
The 12 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 and USB. |
| Special functions | Some pins have special functions, a brief description of which is available in our guide. |
|
The socket . USB A |
The board has a built-in USB controller, which is connected to a USB type A computer socket. |
|
Memory Embedded |
Atmega32u4 is clocked with 16 MHz signal, has 32 kB of Flash 1 kB EEPROM and 2.5 kB SRAM. |
|
Power supply 5 V microUSB |
You can usea5Vpower supply unitwith microUSB connector to power Arduino. |
|
Power supply USB port |
You can power the board from your computer viathe microUSB cable,whilekeeping in mindthat the maximum current capacity of the USB port is 500 mA. Arduino has a system that protects the socket against short circuit and too high current flow. |
|
The connector . ICSP |
The module has ICSP outputs for connecting 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. |
