When using systems cooperating with a computer, there are often problems with their supply.
The use of an external power supply for a circuit that consumes several or several dozen milliamps of electricity is unnecessary and cumbersome.

Recommendations : a project particularly useful for novice electronics who can use their PC as a safe laboratory power supply for microprocessor systems.

The presented system allows you to use the voltage available on the computer's USB connector. On this connector, in addition to two lines for data exchange, 5V voltage is also available, which can be used to power peripheral devices. The maximum current consumed by the connected devices can not exceed 500mA.

The printed circuit board and documentation are included.

A version with a set of independent components is available
