Pool Monitor Device Yieryi BLE-YC01

Hello, could you take a photo of the marking of some chip in your yc01, or just take a photo of the back side of the board. Unfortunately, in my ble-c600 copy, the marking is destroyed. I am interested in a chip with 10 legs, and a msop-10 case. Thanks in advance. If someone else takes a photo, it would be nice, we can compare.

I have been reworking the circuitry of this device for my needs for some time, and it is very convenient that it uses a cheap ble ic. There are certain successes, but for a long time I have not been able to reveal the secret and select this chip for the functionality. There is also no exact marking of three microcircuits approximately: analog switches in the sot23-6 case.

Maybe you can help me, the devices are opened very easily, and there is no particular risk of damaging it, no matter what model you have, could you take a photo of the board of your device, I need to know the marking of the microcircuit, I wrote above, forgive me for writing here, but this is the only place where more or less advanced users of the BLE Y01 series of devices have gathered. You will have a similar scheme:
