I'm decently skilled with basic ic identification methods and lot number cross reference identification for the rebadged chips, but I've ran into a chip I just cannot identify. On the same board there are some chips I could only track down via lot number, so I'm sure this one won't be super simple. This product was made in China, possibly with anti-cloning in mind.
My leads so far: It appears to be the only micro controller on the device. It's driving a small oled display, a few gpio for interfacing, either has a few analog pins for current/voltage reading or it has an offboard chip I don't know about. The Logo looks like Gigadevice, but they don't even make a chip in the same package from what I could tell…

That logo definitely is the GigaDevice logo.
The 28-pin package and the label "F130G6" point to the GD32F130G6U6.
