    Feit Electric a19rgbwagt2r2 9W 800LM RGBW A19 Wi-Fi smart lightbulb
    Tuya cb2l module with BK7231 Wi-Fi mcu chipset. Able to serial flash with teardown, will try to flash with tuya-cloudcutter ota exploit as well and update here with results and OpenBK7231T_App configs.

    Yes, it came with all the flux and junk. The pictures were taken before I removed the module to get at the testpoint on the back. I cleaned it up before buttoning it back up, of course.

    Metal plate of circular shape with a rectangular cutout and holes on a printed circuit board. Interior of Feit Electric bulb showing Tuya CB2L module.
