USB_HUB

Overview

I believe that many engineers, like me, often have USB ports occupied by various debugging tools - -||. Since it is a portable device with only 4 ports, I found this chip in the Lichuang Mall and gave it a headache. . . By the way, after making a TTL, you don’t have to look for and plug in another serial port. It’s practical! ! ! Updated the second version, added a power indicator light, and corrected the problem that the serial port light is always on. Split the dual USB ports into four for easy plugging and unplugging (actually tested, if you use a U disk or serial port tool, it will get stuck)
