LSC Smart XXL LED Strip with LN882HK1 - looking for correct pinout or template

info207 3825 24
Best answers

How can I find the correct pinout or working OpenBeken template for an LSC Smart XXL LED strip with an LN882HK1/LN882HKI chip so the LEDs actually light up?

The strip appears to use GPIOA6 / pin 6 as the data line for the addressable RGB LEDs, pin 7 as an always-high switch for LED power, and pins 11 and 12 as PWM outputs for cold white and warm white, so the RGB part should be configured as an addressable LED rather than a plain PWM channel [#21248135] To identify the exact working mapping, use the Web App’s GPIO Doctor tab and test pins with the high/low buttons to see which ones control the LEDs [#21212857] One user also found the same strip working with a configuration from a separate thread, and another noted that LN882H supports SPI LED modes; WS2812 works on LN882H, while WS2811 timing can differ [#21650067][#21650072][#21650178] A later report says the same strip works, which suggests the hardware is compatible with the shared WS2811/WS2812-style setup rather than a custom unknown template [#21650040]

    Hi guys, I am new to the platform and need help. I have a LSC Smart XXL Led Strip with a LN882HK1 chip, I have flashed it https://www.elektroda.com/rtvforum/topic4027545.html and the Open Beken version OpenLN882H_1.17.656 also latest release, but all config/template what I test, I don't get light on.

    Can someone tell me the correct pinout or template?

    Can you show a photo of your device and the exact IC designation?

    Does the firmware on the LN882H boot at all on the LN688HK1?

    Hello, do you need more information or is this enough?

    Can someone here perhaps give me a working config?

    I had bought 2 strips and have now unpacked the other one, on this one the label of the chip is better recognisable, correct label is LN882HKI - 236AY T16 - AAB M 229.

    Open the "Web App" and find the "GPIO Doctor" tab. Then check each pin with the high and low level setting buttons. Which pins control the LEDs?

    I think I have narrowed it down so far.
    "pins": {
    "6": ? -> GPIOA6 -> Data line for addressable LEDs
    "7": "AlwaysHigh;0", -> Switches on the LED voltage
    "11": "PWM;3", -> CW
    "12": "PWM;4", -> WW
    "20": "Btn;0", -> Button
    "21": "IRRecv;0"
    }

    My only problem now is how to get the LEDs (RGB) to work.

    @p.kaczmarek2 maybe you can help me?

    What does this bar offer in the Tuya app? Can I ask for screenshots of the app? Are the LEDs all the same colour, or are they WS2812B? Are you able to search for the pins that light the LEDs using GPIODoctor?

    Unfortunately, I have never used the Tuya app.
    They are addressable LEDs, so there is only one data line. I looked at the traces and it should be pin 6.
    I have used the strip once with a Bk chip with 16703 and the colours are different, but I could never change colour.

    On the back it says something about WS2811CCT.

    I have the same problem. I have managed to flash the controller. I've already played around a bit in GPIODoctor, but I can't get the warm white and cold white LEDs to light up. The RGB LEDs light up permanently on white, but not at the possible brightness and also not at full length.
    In between, a few "compartments" have flashed in different colours. Has anyone managed to configure the LEDs?

    LN882H supports SPI LED according to this table:
    https://github.com/openshwprojects/OpenBK7231T_App/blob/main/docs/platforms.md
    @insmod would it work on this strip?

    WS2812b works, but i'm not sure about WS2811 - timings are different.

    Side question: in your LN882H port, is timings code shared with Beken? or will we have to figure out a way to support multiple LED types in a multiplatform way?

    Currently it is shared.
    Alternative way is to use native WS2811 in LN882H - requires raw bytes data - no translation.

    The LED strip in this thread is 1:1 the same as mine, including the board with the WS2811. Works with my config so far without any problems.

    Hmm so I think it should be very easy to add official support for LN882H-specific WS2811 driver via my new LED API:
    https://github.com/openshwprojects/OpenBK7231T_App/blob/main/src/driver/drv_dmx512.c
    It actually provides a byte-level interface.... I may try that later today.

    If you need tests, i can try them at home. I have the same strip with LN882H and BK7231's. Both WS2811 strips.

    Ok, but to be sure, WS2812 is not working for you? Timings does not match?

Topic summary

✨ The discussion centers on the LSC Smart XXL LED Strip equipped with the LN882HK1 chip, focusing on obtaining the correct pinout and configuration template to enable LED functionality after flashing with Open Beken firmware (OpenLN882H_1.17.656). The user reports successful flashing and partial activation of features like Hue and MQTT, but the LEDs do not light up as expected. Attempts to identify the correct GPIO pins using the "GPIO Doctor" tool reveal potential pin assignments: GPIOA6 as the data line for addressable LEDs, a pin set to always high for LED voltage, and PWM pins for cold white (CW) and warm white (WW) channels. The LED strip uses addressable LEDs, possibly WS2811CCT type, with a single data line. Some users report RGB LEDs lighting permanently white but without proper brightness control or full length activation, and occasional color flashes in segments. The community seeks a working configuration or template, with no definitive solution provided. Additional details include weak Wi-Fi RSSI, boot status, and MQTT state. The Tuya app's role and LED control via relay roles versus PWM are also discussed but remain unresolved.

FAQ

TL;DR: For LSC Smart XXL LED Strip (LN882HKI) on OpenBeken, users report -72 dBm Wi‑Fi RSSI and "Flash ran smoothly." Flashing works, but LEDs need correct GPIO roles; map pins with on‑device tools before fixing a template. [Elektroda, info207, post #21191735]

Why it matters: This FAQ helps LSC Smart XXL owners ditch Tuya and get working RGB+CCT control with OpenBeken, faster.

Quick facts:

Quick Facts

What’s the working pinout/template for the LSC Smart XXL with LN882HKI?

A complete, verified template is not posted yet. Community testing shows: pin 6 = RGB data (GPIOA6), pin 7 = AlwaysHigh (LED voltage enable), pin 11 = PWM3 (CW), pin 12 = PWM4 (WW), pin 20 = Btn0, and pin 21 = IRRecv. Save roles, then test output. [Elektroda, igfotfrank, post #21248135]

How do I quickly find which pins control the LEDs?

Use the on‑device GPIO Doctor. “Open the ‘Web App’ and find the ‘GPIO Doctor’ tab.” Toggle each pin High/Low and observe the strip. 1. Open Web App. 2. Go to GPIO Doctor. 3. Toggle levels and note reactions. [Elektroda, p.kaczmarek2, post #21212857]

I flashed OpenLN882H but no LEDs light—what should I try first?

Enable the LED rail. Set pin 7 to AlwaysHigh to switch on LED voltage, then test PWM and the addressable data pin. Save, reboot if needed, and re‑test brightness and color. This gate must be on or outputs appear dead. [Elektroda, igfotfrank, post #21248135]

PWM won’t change light—should I try Relay roles in GPIO Doctor?

Yes—verify hardware response first. As advised, test whether LEDs react when you “use Relay roles in GPIODoctor” instead of PWM. If Relay toggles cause visible changes, the wiring and power gating work, and you can fine‑tune PWM later. [Elektroda, p.kaczmarek2, post #21197235]

Which pin carries the RGB data line for addressable LEDs?

Pin 6 (GPIOA6) routes to the strip’s single data line. Assign your addressable LED driver to this pin after confirming LED voltage is enabled. Then test color order and timing. [Elektroda, igfotfrank, post #21248135]

What LED protocol does this strip use—WS2812B or something else?

The strip is marked “WS2811CCT” and uses one data line. Treat it as an addressable LED chain and drive it via the pin 6 data input after enabling the LED supply. [Elektroda, igfotfrank, post #21248567]

How do I enable the CW and WW channels?

Map pin 11 to PWM3 (CW) and pin 12 to PWM4 (WW), then adjust duty via your OpenBeken UI or MQTT. Confirm LED voltage enable on pin 7 first, or CCT will remain off. [Elektroda, igfotfrank, post #21248135]

Why are my RGB LEDs stuck on white and dim, and not the full length?

This symptom was reported. It suggests incomplete configuration: missing LED voltage enable, wrong data pin, or incorrect addressable driver settings. Verify pin 7 is AlwaysHigh, data on pin 6, and then test addressable output. Re‑seat connectors and retest segments. [Elektroda, quegger77, post #21315199]

Does OpenLN882H boot and integrate (Hue/MQTT) on LN882HKI?

Yes. Users flashed OpenLN882H_1.17.656 successfully, enabled Hue, and confirmed MQTT worked for testing. Proceed to role mapping afterward to activate LEDs. [Elektroda, info207, post #21191735]

What does “0 drivers active, total 10” mean after flashing?

It indicates no active Roles yet. Open the UI, assign Roles to the relevant pins (e.g., AlwaysHigh, PWM, Button, IR), Save, and retest. Once roles are set, drivers activate. [Elektroda, info207, post #21191735]

How strong is the Wi‑Fi on this board?

One report showed RSSI at -72 dBm (Weak). Improve stability by testing near your access point during configuration. After mapping, you can relocate the controller. [Elektroda, info207, post #21191735]

Is there a confirmed working template available now?

Not yet in this thread. Multiple follow‑ups ask for a solution, with no posted, final template as of April 2025. Community testing continues. [Elektroda, info207, post #21512118]
