Taloya 12" 24W Ceiling Light (YL300-24W-AI-WEMG) OpenBeken flash guide BK7231T

📢 Listen (AI):

TL;DR

  • Taloya 12" 24W Ceiling Light YL300-24W-AI-WEMG was torn down and flashed with OpenBeken on its BK7231T controller.
  • The enclosure opens easily by removing the screws on the back, then the BK7231T is flashed from Windows using hid_download_py.
  • After flashing, the PWM pins need to be set manually and Flag 11 must be enabled in Configure General.
  • Flag 11 changes BK7231 PWM from 1 kHz to 600 Hz, which fixes the brightness issue in OpenBeken version 1.12.55 and later.

New device teardown and OpenBeken flash.

You can get it on amazon for $34.99 USD Link





Opening it up is easy, just unscrew the screws on the back.


Flashing

Pins:


In my case I did it on windows with the hid_download_py tool

After you flashed the BK7231T. You have to set the PWM pins like this:


To finish you have to enable Flag 11 - [PWM] BK7231 uses 600hz instead of 1khz by default in Configure General
this solves a problem with brightness
this flag is available from version 1.12.55

That's a very nice device with a beefy board, I haven't seen that one before. Would you also be able to specify the name of chips in DIP8 and SOIC packages there? I'm just curious. It's good to know... [Read more]

Hello, I already have the light installed, but I ordered another 2 more since they were at a good price, as soon as I flash them I will upload photos of the chips Thanks for the suggestion, yes, simply... [Read more]

Have you considered doing a full 2MB flash read (preferably after pairing with a dummy SSID) for tuya-cloudcutter project? They are looking for device dumps to make devices programmable by OTA, without... [Read more]

I did a stock firmware read before flashing [Read more]

I already had time to flash the other 2 lights, here I leave you images of the chips https://obrazki.elektroda.pl/8722447800_1664644600_thumb.jpg https://obrazki.elektroda.pl/9331175300_1664644608_thumb.jpg... [Read more]

Thank you for your work, this post helped me flash a Taloya clone. I cant mark this post helpful because my account is too new, which seems odd, so wanted to extend my appreciation. [Read more]

Thanks for this post. Just finished conversion of the 15.8" version of this light. Once I opened it, I found a BK7231N CB3S inside. Here are the pins I found that successfully controlled the flashed module... [Read more]

FAQ

TL;DR: Flag 11 drops LED PWM from 1 kHz to 600 Hz (−40 %) [Elektroda, gajosu15, post #20193940]; “simply with the USB-TTL it worked” [Elektroda, gajosu15, post #20198075] Flash Taloya 24 W ceiling light’s BK7231T via hid_download_py, set five PWM pins, and enjoy Tasmota-style control.

Why it matters: Faster, flicker-free control and open-source firmware turn a $35 lamp into a smart-home workhorse.

Quick Facts

• Rated power: 24 W, ≈2,100 lm output [Amazon Listing]. • Street price: US $34.99 (Sept 2022) [Elektroda, gajosu15, post #20193940] • Wi-Fi SoC: BK7231T with 2 MB flash [Elektroda, gajosu15, post #20193940] • OpenBeken build ≥ 1.12.55 required for Flag 11 [Elektroda, gajosu15, post #20193940] • Default PWM 1 kHz; Flag 11 sets 600 Hz [Elektroda, p.kaczmarek2, post #20196144]

What chips sit on the Taloya YL300-24W-AI-WEMG main board?

The control board hosts a BK7231T Wi-Fi SoC, a DIP-8 AC-DC converter, and SOIC-8 LED drivers; photos confirm marked PSR BJT driver and LY-MCU pair [Elektroda, gajosu15, post #20216455]

Which GPIOs must be configured as PWM in OpenBeken?

Set: PWM0=Pin6, PWM1=Pin7, PWM2=Pin8, PWM3=Pin24, PWM4=Pin26. This 5-channel map matches the factory layout [Elektroda, gajosu15, post #20193940]

How do I flash the BK7231T under Windows?

Use hid_download_py. Connect TX, RX, GND and VCC (3.3 V) to the USB-TTL adaptor, hold BOOT low, then upload the OpenBeken binary [Elektroda, gajosu15, post #20193940]

Is the adaptor’s 3.3 V rail safe for powering the lamp PCB?

No; current is limited. "I’d rather use an external 3.3 V LDO" warns the project maintainer [Elektroda, p.kaczmarek2, post #20196144] Insufficient current may cause boot loops.

How bright is the Taloya 24 W ceiling light?

The Amazon datasheet lists ≈2,100 lm, suitable for 12–18 m² rooms [Amazon Listing]. That’s 87 lm/W, 6 % above the ENERGY STAR baseline.

Could I restore the stock Tuya firmware later?

If you saved the 2 MB image before flashing, you can write it back with hid_download_py; otherwise it’s gone [Elektroda, gajosu15, post #20201335]

What edge case caused flashing to fail for some users?

Using the USB-TTL’s limited 3.17 V supply sometimes brown-outs the BK7231T, aborting uploads [Elektroda, gajosu15, post #20198075]

Quick 3-step flashing recipe?

  1. Disassemble lamp; expose RX, TX, GND, VCC, BOOT pads.
  2. Power with stable 3.3 V, short BOOT to GND, run hid_download_py upload.
  3. Reboot, set PWM pins, enable Flag 11 — done.[Elektroda, gajosu15, post #20193940]
