Feature:
1. This is a frequency meter based on PIC microcontroller, with crystal vibration measurement function and programmable frequency settings.
2. With five-digit digital tube display, the measurement data display is intuitive and convenient.
3. All of them use direct-plug components. The circuit is simple, easy to make, easy to install and debug.
4. The measuring frequency range of this DIY frequency meter is 1Hz-50MHz, which can measure the oscillation frequency of most commonly used crystal oscillators.
5. Five-bit resolution (e.g. 0.0050kHz, 4.5765MHz, 11.059MHz) supports automatic range conversion.
6. Programmable add and subtract frequency settings for measuring equipment such as radio transceivers.
7. The power-saving mode can be selected, and the display can be automatically turned off if the frequency does not change significantly within 15 seconds.
8. Universal USB 5V interface can be used for power supply, or external DC power supply or 9V battery can be used.
