Arduino Yun Mini

Arduino Yun Mini is a breadboard PCB developed with ATmega 32u4 MCU and QCA MIPS 24K SoC CPU operating up to 400 MHz.
You can find the ATmega32u4 datasheet here .
Qualcomm Atheros CPU supports a Linux distribution based on OpenWRT named Linino. The board has built- in WiFi ( IEEE 802.11b/g/n operations up to 150Mbps 1x1 2.4 GHz ) supports 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connector, an ICSP header, two reset buttons and one user button.
The Arduino Yún Mini is similar to the Leonardo in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Arduino Yún Mini to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.

How to use your board

Advanced user


In some countries, it is prohibited to sell WiFi enabled devices without government approval. While waiting for proper certification, some local distributors are disabling WiFi functionality. Check with your dealer before purchasing a Yún if you believe you may live in such a country.

Schematic & Reference Design

Arduino is an open-source electronics platform and here we provide the Arduino Yun Mini Schematics.

  • Ciao - a easy-to-use and powerful technology that simplifies interaction between microcontroller and the "outside World".
  • Bridge - Handles communication between the Linux processor and the Arduino on the Yún.
  • Keyboard - Send keystrokes to an attached computer.
  • Mouse - Control cursor movement on a connected computer.
