The Ele Rexso K is based on a Hi3559 Processor and 16MP Panasonic MN34210 sensor. The camera performs best in its native 4K 30FPS resolution, with 1080p and 2K modes not being as sharp as competitors. Audio is quiet. Video is pretty good at night with lots of detail, however there is a decent amount of noise introduced. The user interface can be somewhat confusing but it is straightforward enough once you figure it out.

I saw this on AliExpress as I was buying a mic adapter. And, well, yeah. It does actually turn on. But I can’t really get it to recharge unless it’s plugged into a computer. If anyone who knows circuit boards better than me can take a look at the circuit board pic (starting at 9:10) and has some feedback I’d appreciate a comment!
