Redesigned Arduino board said to suit space constrained applications

The Arduino Yun WiFi microcontroller board has been redesigned in a more compact housing so that it can be used with a breadboard. This is said to make prototyping easier.

Called the Yun Mini – and available from RS Components – the board has approximate PCB dimensions of 70 x 23mm, less than half the area required by the Arduino Yun PCB. This makes it suitable for use in small spaces, including home automation projects.

The Yun Mini features an ATmega32u4 microcontroller and the Qualcomm Atheros AR9331 SoC, which includes a MIPS 24K CPU running at up to 400MHz. A bridge library enables communication between the two processors, providing Arduino programs running on the ATmega with the ability to run shell scripts, communicate with network interfaces and receive information from the AR9331 processor.

With IEEE802.11b/g/n Wi-Fi running at up to 150Mbit/s, there are 20 digital I/O, 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.
