LED Driver V 2

I’ve just received the PCBs for my next¬†lighting project.¬†It’s a slightly simpler in design but much simpler in build and considerably smaller and cheaper version of my generic LED Driver. This is designed to run off 3 – 4.5v and provides 5 individual ouptuts which are driven by the microcontroller via software written for each specific application.

Complex flashing, fading and sequences can easily be implemented. One output can also be used as an input instead – a connector for a push button switch that can be uses to select different sequences for example.

The board measures just 36mm by 20mm and could happily run for several days continuously on just 2 AAA cells.
