[BK7231N] Avatar ALS08L-B22 Smart Bulb Teardown and OpenBeken Flash Guide Template GPIO

I bought a pack of these bulbs as they were listed as supported under Tasmota but the design seems to have changed to using the Beken BK7231N chip.


The bulbs look pretty basic.
I used a pry tool to pop the plastic cover off



The easiest way to remove the led board is by prying next to the connector as shown in the image



We need to get the second board out and the easiest way to do this is to pry off the two small metal contacts on the bottom of the bulb. Other socket types probably come apart in different ways



When the two contacts are pried off the board just falls out. I put a small black mark on the side where the black wire connects.



We can now inspect the WiFi board to figure out the pinout needed
Here is the pinout needed to flash the firmware



And here is the board once some wires have been soldered to flash the firmware



I only soldered 3 wires as I used the ground pin on the LED board connector for my ground



When using Belkin gui flash tool the software should automatically pick up the configuration of the device from the firmware. I have included it in this guide.

Once flashed the bulbs are ready to be setup. I have done this on two bulbs so far.
