The HK9810B is a ready-to-use RGB LED chaser module based on WS2812B addressable LEDs. The kit includes a 330 mm (13") LED strip with 20 RGB LEDs, controlled by a PIC microcontroller.
The module features 13 pre-programmed lighting effects, including popular modes such as Knight Rider Scanner, GhostBusters, Proton Pack Power, CYLON EYE, and others.
Control is handled via three buttons for program selection, color selection, and speed adjustment. Users can choose between 7 colors and 8 speed levels.
An integrated non-volatile memory stores the last selected program, color, and speed after power-off.
The module and LED strip are powered by 5V DC, with a maximum current consumption of up to 850 mA depending on the selected mode. Power supply or batteries are not included.
Three versions are available depending on power supply:
- Model 9810: 5V DC supply,
- Model 9810B: includes a holder for 4 × AA batteries,
- Model 9810C: 8-28V DC input with built-in DC/DC converter.
LED color shade may slightly differ from photos or videos.
