What microcontroller is inside the Feit OM100/RGBW bulb?
The bulb uses a CB2L module built around the BK7231N Wi-Fi/MCU SoC [Elektroda, mattj, post #20629993]
[BK7231N] Feit Electric - 100W (18W) A21/E26 RGBCW Bulb (OM100/RGBW/CA/AG)
TL;DR
- Feit Electric’s 100W-equivalent A21/E26 RGBCW bulb uses a BK7231N-based CB2L control board and has a different setup from earlier Feit bulbs discussed on the forum.
- The bulb is rated at 18W actual power, 1600 lumens, and 90+ CRI, and the reported configuration uses 5 PWM controls with Flag 8 enabled.
- Smart-bulb modders and teardown readers can use this as a reference for identifying the hardware and flash setup before attempting a similar conversion.
- Tuya CloudCutter was used successfully on firmware version 1.2.16, showing a practical flashing path for this model.
- The post also notes that the board field is still marked TODO, so the hardware documentation is not fully complete yet.
Another RGBCW bulb from Feit Electric... this one has a different configuration than those which have already been discussed here.
