21-key Bluetooth LED controller
This 21-key Bluetooth LED controller manages RGB, RGBW and RGBWW strips from a single DC head interface. It accepts a 5 V to 24 V supply and drives 5050, 2835, WS2811 and WS2812B tape through the Magic Home ecosystem. The unit measures 85 mm by 40 mm by 6 mm and weighs 38 g. Infrared and Bluetooth give a 15 m control range.
Capacity and headroom
The controller dims from 0 % to 100 % across the full 5 V to 24 V window, so short runs and long reels both stay within spec. Addressable WS2811 and WS2812B strips draw more current per metre; the 24 V ceiling limits total wattage before voltage drop appears on very long lengths. It is not suited for builders who need more than 24 V input or individual pixel mapping beyond the built-in modes.
Build integration
A three-core wire connects the DC head to the strip, leaving the PCI bracket slot free for other cards. Infrared and Bluetooth share the same 15 m radius, so the controller can sit behind a side panel without line-of-sight. IP20 rating means it stays inside the chassis, away from moisture. No extra driver software is required beyond the Magic Home app.

Questions about this item
Will the 21-key Bluetooth controller work with my existing 5050 and WS2812B LED strips without rewiring?
Yes, the controller supports 5050, 2835, WS2811 and WS2812B strips via its 3-core DC head connection and 5-24 V input range.
How can I verify the controller is operating correctly after installation?
Pair it over Bluetooth within 15 metres, then use the 21-key remote or Magic Home app to cycle colours and dim from 0 to 100%; the LEDs should respond instantly.
Does the package include the LED strips or a power supply, or must I buy them separately?
Only the 85×40×6 mm, 38 g controller with its 3-core DC cable is included; LED strips and a 5-24 V power source must be purchased separately.
