This project is sponsored by PCBWAY https://www.pcbway.com/?from=MirkoP
A frequency meter, also known as a frequency counter, is a device or instrument used to measure the frequency of an oscillating signal. This time the frequency meter uses an inexpensive STM32 microcontroller and this time, thanks to his better perfomances of the MCU, the frequency range is from 0 to 30 MHz, and therefore it is ideal for use in HF radio devices .
The device is really simple to build and consists of several components
STM32F103C6 or STM32F103C8 microcontroller board
8 Digit 7 Seg Display module
and one 100nF capacitor
This is an incredibly inexpensive measuring device, the total cost of which does not exceed a few dollars, and is an indispensable instrument in any laboratory.
