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.

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.
