Today, a short topic - the interior of a very cheap LED strip controller, available for purchase on a Polish auction website, offering WiFi control, remote control and playing to the rhythm of music. This time there will be a not-so-known WiFi microcontroller inside, the TR6260S1, which has only been mentioned on our forum only once or twice. At the moment, I don`t know if it`s possible to change the charge, but if I make progress, I`ll try to document what I found here.

Purchasing an LED strip
You can get the belt from the Krasław importer, although we know that it is produced in China and the importer only sticks its logo on it. Here is a screenshot of the auction:

Specification:

There are no markings on the packaging:

The set doesn`t even include a strip of tape to attach the strap:

The inside of the controller
We pry the cover and experience an unpleasant surprise - inside there is a very unknown microcontroller with WiFi:

TR6260S1... there is some information about it on the Internet:

The pinouts are also described, and there is even some information about the boot mode that reminds me of ESP:

There are RX, TX and BOT (BOOT) signals on the PCB. I experimented with them a bit, I tried using various programmers from the Internet, also using various similar exotic systems, and I even experimented with Esptool.py, but to no avail. It`s a different microcontroller.
There is also a microphone on board, which means the strap can respond to sound.

There is a step down converter in the power supply block, because something must generate 3.3V for the WiFi module from the 12V we have at the input.
The transistors have the SMD 3400 code, so probably:

During experiments:

I searched on Github, even in the source codes themselves:
https://github.com/search?q=TR6260&type=code
For example, newracom nrc7292 sdk seems to have support for this chip:
https://github.com/newracom/nrc7292_sdk
but at the moment I have the impression that something is still missing.
https://github.com/search?q=repo%3Anewracom%2Fnrc7292_sdk%20TR6260&type=code

Here is the boot log from this system:

The name of the platform is clearly visible in the log: tr6260 .
Indeed, this is one of the platforms supported by Tuya:

Manufacturer	Chipset platform	Type
BEKEN	BK7231N	Tuya standard chip
Realtek	RTL8720CF	Tuya standard chip
Realtek	RTL8720DN	Tuya standard chip
Realtek	RTL8710BN	Tuya standard chip
ESWIN	TR6260	Third-party chip
AltoBeam	ATBM6431	Third-party chip
Lightning Semiconductor	LN8825	Third-party chip
Bouffalo Lab	BL602	Third-party chip

Additionally, on Aliexpress, I found a development board with a similar module, but there was no information there about what tools can be used for this TR

Summary
Unfortunately, I have to advise against this product—unless you're fine with using the manufacturer's cloud. Personally, I was hopeful we could free it from the cloud, which would have been easy if it had an ESP8266 or ESP32 inside (then Tasmota could save us), or if it was built on BK7231N or T, BL602, XR809, W600, or W800 (then we could flash OpenBeken). What's worse, the WiFi microcontroller is directly on the PCB, so changing it to an ESP module isn't possible, and that would be irreversible anyway...
In summary, there's no room for experimentation. If any of the readers find more information about the TR6260S1, please share.
I've been researching this topic myself:
https://www.elektroda.com/rtvforum/topic3960571.html
But there are no specifics; the SDK isn't complete, and I haven't found a flasher for this version either.
If anyone knows or finds anything more, please let me know.
PS: Additionally, I have a feeling that considering the transistors inside, the 144W is a bit exaggerated, but that's already standard in these types of products...

Since you have already described a lot of different devices, some could be flashed, some could not, I have an idea. Maybe in the section we could permanently pin a post with a table - device + infor whether it is reflashable, and additional information - it works in the manufacturer`s cloud, works standalone, etc. This would be very useful for buyers. At the same time, it would promote knowledge about problems with such devices.

It`s a good idea, but doesn`t something like this basically already exist?

We have a topic:
Global list of interior IoT devices (ESP8266, BK7231, BL602, W600, etc.)
which basically links to mine electrode-friendly page/aggregator of links to Elektroda from Github:
https://openbekeniot.github.io/webapp/devicesList.html
The list includes a convenient search engine (by model name, description and tags) for devices, shows one photo of the device and allows you to quickly find the appropriate topic on Elektroda.

The list itself is made by the community, and its source can be found here:
https://github.com/OpenBekenIOT/webapp
more specifically, here is the "database" in JSON:
https://github.com/OpenBekenIOT/webapp/blob/gh-pages/devices.json
Anyone can open a pull request and add an entry, I try to do it myself from time to time to keep the list up to date. This topic will also be added to this list when I find some time.

It is also worth noting that the mentioned list of devices includes both products supported by OpenBeken and those that are not yet supported. In the case of supported products, the list also offers access from the firmware level to be able to configure the device with one click:

(sorry for the bad image of the device in the screenshot, I`m on mobile internet, everything loads slowly, there is a good image in the database...)
This is a screenshot from Web App OBK, this is what access to the list of devices looks like in the firmware (or rather in the web app, but it`s not important). There are also links to the forum, to a topic discussing the device, etc.

PS: Just as a curiosity, I would like to add that an attentive reader will note that in the screenshot there is a local IP address and there are mentions of Windows - this is not a mistake, my software simply supports Windows (together with all MQTT, etc.), and has a primitive simulator for Windows, which allows me to quickly test things even when I don`t have the hardware at hand. Below is a screenshot from the simulator:

Spoiler:

So, to sum up, the list is basically there and with a good search engine, the only thing you can think about is how to improve it (better interface, support status, etc.), because with the number of 366 entries (at the time of writing the post) it is simply necessary to keep it just posting on the forum would be impractical. The mini site on Github is better, and it still links to us (Electroda).

I didn`t even know. Pretty cool. Tylok IMHO, it would be worth highlighting it somehow and at least making a new sticky post with information on why to reflash the firmware at all, a short guide and a search engine for compatible equipment.

A very good idea, although I actually had that in mind. You could also mention how to start the game, what is the cheapest, and how to control it (e.g. through the very primitive Tasmota Control for a phone and device with a static IP address).

As for the list itself, you could also think about better displaying the support status, I`ll think about it.
