Squareware mini board features chain-able LED matrix

Not long time ago we featured a SquareWare 2.0 wearable Arduino board. Now Ray has introduced another version of SquareWare Mini board which also features same Atmega328p microcontroller but is smaller in size and also packs few new features.

In the feature list we can see push button, USB which can be used with V-USB library. Also buzzer, temperature sensor, light sensor, couple of MOSFETs and Lithium batter battery jack. In this mini version coin cell battery holder has been removed what allows to shrink board to smaller size. But probably most exciting feature is RGB LED matrix support which also can be chained in to larger display. You can find project details and software files in GitHub.
