The SP638E is a Bluetooth addressable RGB LED controller for pixel strip on DC 5-24V. It speaks the single-wire SPI protocol used by WS2812B, WS2811, WS2813, WS2815, UCS1903, GS8208 and TM1804/1812 tape, so each LED can run its own color — chases, rainbows, meteors and music spectrums rather than one flat color.
What This Controller Works With
- Addressable RGB strip on single-wire (RZ-coded) ICs: WS2812B, WS2811, WS2813, WS2815, UCS1903/1909, GS8206/GS8208, TM1804/1812
- RGB pixel FCOB / COB strip and pixel modules, at 5V, 12V or 24V
- Up to 600 driver ICs on one controller, wired VCC / DAT / GND
Not compatible with: Plain 4-pin RGB tape with no IC (use the SP633E) and clock-based two-wire ICs such as WS2801, APA102 and SK9822, which need a separate data and clock line.
Key Features
- SPI addressable RGB control with per-pixel color
- Dynamic, music-reactive and DIY effects with adjustable speed, direction and segment length
- Effect collection for saved scenes
- Three music capture modes: phone microphone, player streaming, or the onboard microphone
- Color-order calibration (RGB / GRB and so on) plus ON/OFF animations and timers
- OTA firmware updates
App and Remote Control
BanlanX Bluetooth App
BanlanX pairs over Bluetooth with no WiFi, hub or account. Set your IC type, pixel count and color order once, and the effect library is ready to run.
Optional 2.4G Touch Remote and Wall Panel
SP638E also pairs with the optional RB3 / RC3 2.4G touch remote and 86-type wall panel (sold separately). One remote can drive several controllers, each controller binds up to 5 remotes, and the system supports unified ALL control or 4-zone control.
Wiring and Installation
Feed a regulated DC 5-24V supply into the controller input, then wire the strip to the VCC / DAT / GND output terminals as shown on the wiring diagram. Data is directional: wire DAT to the arrow-in end. If colors come out swapped, fix the color order in the app rather than rewiring.
- Match the supply voltage to the strip: a 24V strip on a 12V supply will look dim, and the reverse will damage it.
- Keep total load inside the controller rating, and add a second supply or a power repeater on long runs.
- Mount the controller somewhere ventilated and dry — the housing is IP20 and not for outdoor or damp use.

Not Sure Which Model You Need?
The quickest check is to count the pads on the end of your strip and look for a chip marking. Two pads means single color, three means tunable white, four means RGB, five means RGBW and six means RGBCCT. A marking such as WS2812B, WS2811, SK6812 or WS2805 means the strip is addressable and needs an SPI model.
- Pick the SP633E RGB LED Strip Controller if your RGB strip has no IC and 4 pins.
- Pick the SP639E Addressable RGBW Controller if your pixel strip is RGBW (SK6812 and similar).
- Pick the SP63BE Addressable RGB + Single Color Controller if you also have a separate white strip to run.
- Pick the SP630E All-in-One LED Strip Controller if you want one controller that covers every strip type.
