Yún Board
What is Arduino Yun? – Arduino Yún is a microcontroller board released by Arduino cc. This is a board that combines an Arduino AVR microcontroller with a Linux controller based on the Atheros AR9331 processor. This makes this board capable of running more complex applications and can be connected to the internet easily.
Specification
Following are the complete specifications between AVR and Atheros processors in tabular form for Arduino Yún:
| PROCESSOR | AVR (ATMEGA32U4) | ATHEROS AR9331 |
|---|---|---|
| Architecture | 8-bit | 32-bit |
| Clock Speed | 16 MHz | 400 MHz |
| Memory | 32 KB flash, 2.5 KB SRAM, 1 KB EEPROM | 64 MB DDR2 RAM |
| Connectivity | USB, UART, SPI, I2C | WiFi, Ethernet |
| Number of I/O pins | 20 | 10 |
The AVR processor (ATmega32u4) is a processor used on a standard Arduino board whose job is to run uploaded programs. Meanwhile, the Atheros AR9331 Processor is the processor used on the Arduino Yún board to run the Linux operating system and manage Ethernet and WiFi connectivity.
AVR processors are used to control hardware devices such as I/O pins, while Atheros processors are used to controlling software such as network connectivity and file systems.
Advantages
The following are some of the advantages of the Yun board:
- Can be connected to the internet easily
- Can run more complex applications
- Has Linux Command Line Interface (CLI) support
- Has a micro-SD slot for data storage
- Equipped with WiFi and Ethernet
Disadvantages
The following are some of the disadvantages of the Yun board:
- The price is more expensive than other Arduino boards
- Requires more power
- Requires more space to install
When to use Arduino Yún?
Arduino Yún is suitable for use in projects that require internet connectivity and can run more complex applications. For example, IoT projects, remote monitoring systems, and control of smart home devices. However, if your project doesn’t require internet connectivity or complex applications, you can use other Arduino boards that are cheaper and less power-consuming. Hopefully, this simple article about What Arduino Yún can be useful.
