Wide input voltage range (DC 5–24V): lets you work with common 5V, 12V and 24V LED systems, reducing the need for multiple controllers or power conversions. Compact 'mini' form factor: fits into tight spaces and is easy to install behind panels, inside enclosures, or in decorative lighting fixtures. 38key remote included: provides onthefly access to color selection, mode changes, brightness and speed adjustments without reprogramming. What this product does Controls addressable RGB LED lights that use WS2811, WS2812B or SP6812 driver chips. Accepts a DC power supply from 5 to 24 volts and outputs control signals to compatible LED strips. Offers remote control via an included 38key remote for instant, wireless operation. Main features and specifications Model: SP621E Mini Controller (WMSP621EUSB) Compatibility: WS2811, WS2812B, SP6812 addressable LED chips Input voltage: DC 5–24V Control: 38key infrared remote control included Size: mini form factor for compact installations Ease of use: plugandplay with compatible LED strips and a matching power supply How it helps you Saves time: avoid reconfiguring multiple controllers for different strip types — one controller supports several common addressable LEDs. Simplifies installation: compact size and a broad voltage range make placement and power choices more flexible. Improves control: the 38key remote gives immediate access to color, brightness, and dynamic effects without needing extra hardware or software. Typical use cases 1) Home accent lighting — control addressable LED strips under cabinets, behind TVs, or along ceilings to set color and mood using the remote. 2) Event and stage lighting — quickly change effects and brightness for small stage setups, DJ booths, or photo backdrops where compact controllers are needed. 3) Custom signage and architectural features — integrate the mini controller into lighted signs or facades that use WS281xcompatible LEDs and require remote operation. What's in the box SP621E Mini Controller (WMSP621EUSB) 38key IR remote control User connection points for DC input and LED output Installation notes Use a compatible DC power supply that matches your LED strip voltage (5V, 12V, or 24V). Confirm LED strip compatibility (WS2811, WS2812B, or SP6812) before connection. Position the mini controller where the IR remote signal can reach the receiver, or place it where a direct line of sight is available if required. Why choose this controller Broad compatibility and flexible power range reduce the need to stock multiple controllers. Compact design makes it practical for a wide range of installations. Included 38key remote provides convenient, immediate control of colors and effects. Technical reminders Verify your LED strip voltage and power requirements prior to connection. Follow standard electrical safety practices when wiring power and LEDs. If using the WMSP621EUSB designation in documentation or ordering, confirm the model matches the DC 5–24V specification and included remote.
