The SP631E is a Bluetooth single color LED strip dimmer controller for 2-pin tape running on DC 5-24V. It replaces a basic inline dimmer with high-frequency PWM brightness control from the free BanlanX app, plus music-reactive effects and on/off timers — and it still works from a wall panel or remote if you would rather not reach for a phone.
What This Controller Works With
- Single color LED strips with 2 pins (V+ and V-) at 5V, 12V or 24V
- SMD tape such as 2835, 3528, 5050 and 5630, plus single color FCOB / COB strip
- Any single-channel low-voltage LED load inside 6A per channel and 12A total (up to 288W at 24V, 144W at 12V)
Not compatible with: RGB, CCT/tunable white, RGBW or RGBCCT strips — count the pins on your tape and pick the matching model below. Addressable (IC) strips need an SPI controller, not this PWM model.
Key Features
- 1CH high-frequency PWM dimming for smooth, flicker-free brightness across the full range
- Built-in dynamic and music-reactive effects
- Three music capture modes: phone microphone, player streaming, or the onboard microphone
- ON/OFF timers set in the app
- OTA firmware updates
- Binds up to 5 remotes; unified or 4-zone control
App and Remote Control
BanlanX Bluetooth App
Turn on Bluetooth, open BanlanX and the SP631E appears in the device list — no WiFi, no account and no hub required. From there you can rename the device, set brightness, pick effects, schedule timers and run firmware updates.
Optional 2.4G Touch Remote and Wall Panel
SP631E also pairs with the optional RB1 / RC1 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 V+ / V- output terminals as shown on the wiring diagram. Match the strip polarity to the V+ and V- terminals — a reversed single color strip simply will not light.
- 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 SP632E CCT / Tunable White Controller if your strip has 3 pins (warm + cool white).
- Pick the SP633E RGB LED Strip Controller if your strip has 4 pins (RGB).
- Pick the SP636E Addressable Single Color Controller if your strip is addressable single color with an IC.
- Pick the SP630E All-in-One LED Strip Controller if you want one controller that covers every strip type.
