Does anyone recognise the logo on U7 in this photo?

This is the product:

I have identified most of the other major ICs:

The logo is Winnermicro, but the exact IC is hard to tell, possibly W600 series. It is a wireless MCU, but I guess it is just used as a cheap general purpose MCU here.

Although on the slanted view it looks like it has W800.

To me it looks like a W806. A W800 has 32 pins.

Many thanks.

This is the Chinese product page for the W806 (no English version):
