Teardown, Flashing & Basic Info of Anwio AN-G250-1XD W LED Bulbs with Tuya WBLC9

This is a quick teardown of the Anwio AN-G250-1XD W 120V Y 4.9W 72mA 120VAC @ 60Hz 2700K-6500K 23/22K @ 350 Lumens. I picked these up in a 2-pack on Amazon (ASIN B08TGZ5F92) for $8.69 USD. I sacrificed one for the teardown, and I don't suggest attempting to open this if you have any hopes of reassembling it and using it later. Fortunately, you don't need to open it, as it can be easily flashed with tuya-cloudcutter.

Basic Info:
The bulb is powered by a Tuya WBLC9 with a BK7231T SoC. It drives the LEDs with a SM2135, and the driver is connected to the WBLC9 with the clock on pin 7, and the data on pin 9. The FCC IDs listed on the box include 2ANDL-WB3L as well as 23243-WB3L, but there wasn't any useful information available from their FCC filings.

Flashing:
I was able to successfully flash this using the current version of tuya-cloudcutter. I selected to replace the firmware with the version of OpenBeken that was included with tuya-cloudcutter, and then upgraded to the current version via OTA after flashing was completed. In tuya-cloudcutter, I selected firmware version 2.9.16, as this was what was shown in the Smart Life app prior to flashing.
