This is a frequency meter based on PIC single chip microcomputer, with crystal oscillator measurement function and programmable addition and subtraction frequency setting, five digit nixie tube display, convenient and intuitive, all use in-line components, simple circuit and easy to make.
Circuit features:
Measurable frequency range: 1hz-50mhz (1hz-50mhz);
It can measure the oscillation frequency of most common crystal oscillators;
Five bit precision resolution (e.g. 0.0050 kHz, 4.5765 MHz, 11.059 MHz);
Automatic range conversion without manual switching;
Programmable addition and subtraction frequency settings are used to measure equipment such as radio transceivers;
Power saving mode can be selected. If there is no obvious change in frequency within 15 seconds, the display will be automatically turned off;
The universal USB 5V interface can be used for power supply, and external DC power supply or 9V battery can also be used.
The number of components is small, all in-line components, and the installation and commissioning are simple.

The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.
In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.
All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.
This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
