Flashing Tuya Smart Plug with CB2S Module and BK7231N Chip: Pinout and Process

Today we are flashing another tuya smart plug.

The plug was purchased in a local store for 3 EUR, which is good price for it.

Some photo of device and packaging:


It can be opened from the downside unlike most similar plugs. The cover doesnt glued to the case, but instead uses a plastic lockers on the corners.
This devices uses CB2S module. Flashing process is exactly same as for this one, so I will skip details here.

Pinout:
- BL0937 SEL on P6
- Button (channel 1) on P10
- BL0937 VI on P7
- WiFi LED on P26
- BL0937 ELE on P8
- Relay (channel 1) on P24
Device seems to be using CB2S module, which is using BK7231N.
And the Tuya section starts, as usual, at 2023424

Note that there is no red led for monitoring power state.
