description: This work is devoted to the development of a device for checking the parameters of capacitors. A schematic diagram of the device is designed. The printed circuit board with placement of all radio elements is designed. A device capable of measuring the capacitance of capacitors, measuring the equivalent Series Resistance of the capacitor (Equivalent Series Resistance), the main parameter of electrolytic capacitors, has been developed. The device is controlled by the STM32 microcontroller, which allows you to develop and create devices on operating systems with complex software. The paper presents analogs of measuring devices and their characteristics. In this work, the following tasks were considered and performed during the development: - Analogs of devices for measuring the parameters of capacitors available on the market are given. Their advantages and disadvantages, technical characteristics and parameters of signal processing are taken into account. - A schematic diagram of the device being created has been developed - The selection of the element base is made - Printed circuit board developed - The structure of the device operation is described - The algorithm of operation is considered As a result of this work, a device measuring the parameters of capacitors will be designed and developed, which will perform the necessary measurements. Capacitors are used in almost all modern devices. The capacitance meter of capacitors is important and well-demanded in radio engineering, since capacitance meters on microcontrollers are easy to use and have small dimensions.
