mini usb-hub

Overview

A relatively small USB-hub, based on SL2.1A, only requires a mobile phone's typec data cable to be used, without the need to install additional drivers, reducing the storage volume and making it convenient for people traveling on business.

The circuit has a self-restoring fuse for circuit protection, and the power indicator light can be welded with a larger resistance resistor to reduce the brightness.

20211104 update

A 3D shell has been added. Please note that the board must be 0.8mm thick, otherwise the 3D shell cannot be installed. See the attachment for the 3D shell.

The top screws use M3*5, the bottom screws use M3*8, and the middle copper pillar uses M3*8.

See the high-definition video at Station B , and the demonstration at Station B

Have you ever heard of negative frequencies?
For example, the RF signal is -590M----610M. After down-conversion, it becomes a baseband signal of -10M---10M. After AD conversion, can the negative frequency here be sampled by A/DC? In other words,
