This driver can be used with a large range of RGB LEDs, LED array modules or indvidual LEDs.
The firmware programmed into the PIC microcontroller generates an 8 bit resolution PWM signal on 3 output channels. The outputs control three power MOSFETs that when connected to Red, Green and Blue LEDs are capable of generating a huge range of colours and effects.
The kit comes complete with a pre-programmed PIC microcontroller that includes a range of colour fading and strobe effects. User control is via a single push button switch which has three functions:
1. Short press, Freeze / Run the current effect
2. Double press, steps to the next effect
3. Long press > 1.5 seconds puts the driver into standby , holding the switch for a further 1.5 seconds turns it back on.
The current freeze / run state, colour and sequence are all saved to NVRAM so the driver always powers up using the last sequence and state.
