What hardware sits inside the MOKO C37 E14 bulb?
The driver uses a BK7231T Wi-Fi SoC, BP1633 LED controller for dual-white, and three transistors for RGB output [Elektroda, p.kaczmarek2, post #20558400]
[BK7231T/FL_M44_V1.6.1z??] MOKO Smart Bulb C37 E14 5W 400lm
TL;DR
- MOKO Smart Bulb C37 E14 5W 400lm teardown and OpenBeken conversion centers on a BK7231T-based Wi‑Fi module marked FL_M44_V1.6.1z?.
- Inside, BP1633 controls the warm and cold white LEDs, while three transistors drive the RGB channels.
- The six-pack cost $23.52, and flashing used BK7231GUIFlashTool with five PWM pins: P26, P24, P7, P6, and P8.
- Flashing succeeded, and the bulb worked in the OpenBeken panel afterward.

Here is a short presentation of the interior, firmware change and a template for the MOKO Smart Bulb C37 E14 5W 400lm LED lamp built on the basis of a rather unusual WiFi module with BK7231T. Materials for this topic were sent to me by user @dedamraz, so this time it will be short. We'll just upload OpenBeken and free the lamp from the cloud.
The package contains 6 pieces and was bought for $23.52 in a local store in Serbia:
We remove the dome. LEDs are controlled by BP1633 (warm and cold white) and three transistors (on RGB):
We take off the PCB with LEDs:
You can already see the BK7231T:
You need to desolder it:
WiFi module, can anyone read the marking? FL_M44_V1.6.1z?:
The batch can be uploaded via:

Then you need to set the 5 PWM pins that control the colors.
Testing:
Works!

- LED Blue (Channel 3) on P7
- LED Cool (Channel 4) on P6
- LED Warm (Channel 5) on P8
Summary
Thank you my friend for sharing the material with me. The entire six-pack can already work with OpenBeken. The module from the inside turned out to be quite interesting, I think it will be worth adding it to our list of devices. All its markings are signed, so there were no problems with changing the firmware.
I am attaching a batch backup.
