Feature:

Product Color: See pictures

This is a PIC microcontroller based on the frequency meter, with a crystal measurement function and programmable addition and subtraction frequency settings, five digital display, easy and intuitive, all use of in-line components, the circuit is simple and easy to produce.

Circuit characteristics:

Measurable frequency range 1 Hz -50 MHz

Can measure the oscillation frequency of most commonly used crystal;

Five precision resolution (eg 0.0050 kHz, 4.5765 MHz, 11.059 MHz);

Automatic range conversion, without human switching;

Programmable addition and subtraction frequency settings for the measurement of radio transceivers and other equipment;

You can select the power saving mode, if the frequency is not obvious changes within 15 seconds automatically turn off the display;

You can use the universal USB 5V interface power supply, can also use an external DC power supply or 9V battery.

The number of components is small, all straight-line components, installation and commissioning simple.
