It comes with firmware which allows it to be used as a smart display peripheral with a host system. There is a bar-graph mode. There are two dot-matrix character sets – 5x7 for one character, or 3x5 to display two characters side-side. There is also a raw mode where each individual led can be accessed.
Nova SMT Blinky uses an Microchip ATtiny 85 Processor. It can operate from 3 1.5V batteries or a 5 volt supply. It can be driven with either 5V or 3.3V systems.
When supplied just power, Nova SMT Blinky will come up in 'demo' mode, showing off its various capabilities and special effects.
An Arduino-compatible library is available which can be used drive Nova SMT Blinky as a display peripheral
