The HK9920 RC LED lights kit is a fully assembled module designed for controlling lighting effects in RC models, scale models, and electronic hobby projects. The device features four independent output channels for driving LEDs or LED modules.
The controller is based on a PIC microcontroller and offers 17 pre-programmed lighting effects, as well as a demo mode. In demo mode, all available programs are played sequentially.
Program selection is done via a push button, and the effect speed can be adjusted. The module includes non-volatile memory, which stores the last selected program and automatically restores it after power cycling.
Each output channel is connected via wires approximately 300 mm long, making installation in RC models and enclosures easy. The wide supply voltage range allows use in various applications.
