The USB socket is one of the electrical interfaces with high frequency of daily use. It is often used for power supply, unless USB HUB is used as an interface for expansion during data transmission. HUB is a hub that people often say, such as computers and notebooks. If the USB interface is not enough, the USB HUB will be selected for expansion. Then, if you need to use multiple USB devices on a daily basis, you only need to supply power, but if the interface is not enough, you can make a simple USB power take-off splitter, then you can output multiple power supplies on one interface. Of course, you have to The normal use of each device can be guaranteed only when the power supply USB power is sufficient.

So how do you make a USB power take-off splitter yourself?

P01 USB take-up splitter

First, preparation for production

1, renderings

Let's take a look at the finished product of the USB power take-off splitter. The effect of 1 minute 4 is mainly composed of 1 USB bus and 4 USB sockets. The USB bus is used as the input of the power supply, and the four USB sockets are connected in parallel as the output to realize the function of 1 minute and 4:

Second, the design principle

1, the principle

The circuit principle of this work is very simple, mainly using the parallel output of the USB female. The red LED acts as a power indicator.

Third, DIY process sharing

Prepare 4 USB sockets, solder the wires according to the definition of their pins. The main pins are VCC and GND, and the other two data lines are floating:
