[Training Camp_Basic Class] Hub based on GL3520-OS322

Overview

USB3.0 high-speed hub based on GL3250-22 chip, GL3520-22 is a 4-port, low-power and configurable hub. And backwards compatible with all USB 2.0 and USB 1.1 hosts. The chip has a built-in 5v-3.3v voltage regulator. Up to eight devices can be connected (matryoshka warning). Because I'm not very skilled, my drawing of PCB is rather poor. I’ll revamp it when I have time (I’ll definitely do it next time). I haven't received the board yet, so I don't know if it can be used.

Motor Control of Wind Power Pendulum
I use a coreless motor, but it can't push the pole (it's not heavy, very light). Why is that? In the video, the coreless motors spin very fast and fly high in a flash. I can't even get it up at 10 deg
