RS now supplying Arduino mini wireless development board

12 July 2015

RS Components is extending its Arduino portfolio of open-source electronics development and prototyping boards with the addition of the new Arduino Yun Mini.

Aimed at embedded engineers, hackers and students, the Arduino Yun Mini is a redesign of the Arduino Yun WiFi microcontroller board and has been re-engineered to be used with a breadboard, making prototyping easier, and also provides its functionality in a light and highly compact package.

The Yun Mini offers an affordable breadboard PCB with an ATmega32u4 microcontroller and the Qualcomm Atheros AR9331 system-on-chip IC with a MIPS 24K CPU, which operates at up to 400MHz and supports a Linux distribution based on OpenWRT called Linino.

A bridge library enables communication between the two processors, providing Arduino programs the ability to run shell scripts, communicate with network interfaces and receive information from the AR9331 processor.

The board has built-in WiFi (IEEE 802.11b/g/n operation up to 150Mbps) and supports 20 digital input/output pins, seven of which can be used as PWM outputs and 12 as analogue inputs. Other specifications include a 16MHz crystal oscillator, a micro-USB connector, an ICSP header, two reset buttons and one user button.

The Yun Mini can be customised from a choice of up to two out of three available accessories, which are the dogRJ45, the dogUSB and the dogUSB eMMC. The dogRJ45 is a 10/100Mbps Ethernet port; the dogUSB is a USB A type connector with USB 2.0 hub that features a slot for a mini SD to extend the memory of the board; and the dogUSB eMMC is a USB port type A with an integrated 4GB of Flash.
