What hardware is inside the CoRui 9 W RGBCW bulb?
Most units carry a BK7231N Wi-Fi SoC on a WB2L-M1 module; some later batches use a BL602-based BL-200 module [Elektroda, #20262993; #20378459].

TL;DR
- CoRui TUYA WiFi Smart LED Light Bulb 9W E27 RGBCW uses a BK7231N and gets a brief unboxing plus teardown check.

I found only U1 (BP2525 - not sure if BP ,it's very hard to see) and U2 (YT5202A).I think it is using PWMs, but not sure. Which pins are 3.3,GND,TX and RX? i can't find datasheet for BL-200 module. Link... [Read more]
Please modify your post to include screenshots from the Aliexpress offer. Aliexpress links expire after some time and then becomes inaccessible. BP2525 is a power supply chip. It's not a LED driver. I... [Read more]

Sorry, I didn't flash it yet. I must remember where I have put that bulb. I have so much disassembled devices for the sake of OBK that's it's easy to get lost. BL602 is not very popular, but here is a... [Read more]

@ionoleinic As far as I know, there is no way to read the current flash dump, but I will admit it upright: we didn't do much BL602 research. It's a very rare platform. You can try Googling yourself if... [Read more]
